-
class
genometools.misc.
classmethod
(function) → method¶ Convert a function to be a class method.
A class method receives the class as implicit first argument, just like an instance method receives the instance. To declare a class method, use this idiom:
- class C:
@classmethod def f(cls, arg1, arg2, ...):
...
It can be called either on the class (e.g. C.f()) or on an instance (e.g. C().f()). The instance is ignored except for its class. If a class method is called for a derived class, the derived class object is passed as the implied first argument.
Class methods are different than C++ or Java static methods. If you want those, see the staticmethod builtin.
-
genometools.misc.
cmp
(x, y) → integer¶ Return negative if x<y, zero if x==y, positive if x>y.
-
genometools.misc.
coerce

-
genometools.misc.
compile
(source, filename, mode[, flags[, dont_inherit]]) → code object¶ Compile the source string (a Python module, statement or expression) into a code object that can be executed by the exec statement or eval(). The filename will be used for run-time error messages. The mode must be ‘exec’ to compile a module, ‘single’ to compile a single (interactive) statement, or ‘eval’ to compile an expression. The flags argument, if present, controls which future statements influence the compilation of the code. The dont_inherit argument, if non-zero, stops the compilation inheriting the effects of any future statements in effect in the code calling compile; if absent or zero these statements do influence the compilation, in addition to any features explicitly specified.
-
class
genometools.misc.

configure_logger
(name, log_stream=<open file '<stdout>', mode 'w'>, log_file=None, log_level=20, keep_old_handlers=False, propagate=False)[source]¶ Configures and returns a logger.
This function serves to simplify the configuration of a logger that writes to a file and/or to a stream (e.g., stdout).
Parameters: - name (str) – The name of the logger. Typically set to
__name__
. - log_stream (a stream object, optional) – The stream to write log messages to. If
None
, do not write to any stream. The default value issys.stdout
. - log_file (str, optional) – The path of a file to write log messages to. If None, do not write to
any file. The default value is
None
. - log_level (int, optional) – A logging level as defined in Python’s logging module. The default
value is
logging.INFO
. - keep_old_handlers (bool, optional) – If set to
True
, keep any pre-existing handlers that are attached to the logger. The default value isFalse
. - propagate (bool, optional) – If set to
True
, propagate the loggers messages to the parent logger. The default value isFalse
.
Returns: The logger.
Return type: Notes
Note that if
log_stream
andlog_file
are bothNone
, no handlers will be created.- name (str) – The name of the logger. Typically set to

-
genometools.misc.

newdict
-
genometools.misc.
dir
([object]) → list of strings¶ If called without an argument, return the names in the current scope. Else, return an alphabetized list of names comprising (some of) the attributes of the given object, and of attributes reachable from it. If the object supplies a method named __dir__, it will be used; otherwise the default dir() logic is used and returns:
for a module object: the module’s attributes. for a class object: its attributes, and recursively the attributes
of its bases.- for any other object: its attributes, its class’s attributes, and
- recursively the attributes of its class’s base classes.
-
genometools.misc.

-
class
genometools.misc.
enumerate
(iterable[, start]) → iterator for index, value of iterable¶ Return an enumerate object. iterable must be another object that supports iteration. The enumerate object yields pairs containing a count (from start, which defaults to zero) and a value yielded by the iterable argument. enumerate is useful for obtaining an indexed list:
(0, seq[0]), (1, seq[1]), (2, seq[2]), ...-
next
¶
-
-
genometools.misc.
eval
(source[, globals[, locals]]) → value¶ Evaluate the source in the context of globals and locals. The source may be a string representing a Python expression or a code object as returned by compile(). The globals must be a dictionary and locals can be any mapping, defaulting to the current globals and locals. If only globals is given, locals defaults to it.
-
genometools.misc.
execfile
(filename[, globals[, locals]])¶ Read and execute a Python script from a file. The globals and locals are dictionaries, defaulting to the current globals and locals. If only globals is given, locals defaults to it.
-
class
genometools.misc.
file
(name[, mode[, buffering]]) → file object¶ Open a file. The mode can be ‘r’, ‘w’ or ‘a’ for reading (default), writing or appending. The file will be created if it doesn’t exist when opened for writing or appending; it will be truncated when opened for writing. Add a ‘b’ to the mode for binary files. Add a ‘+’ to the mode to allow simultaneous reading and writing. If the buffering argument is given, 0 means unbuffered, 1 means line buffered, and larger numbers specify the buffer size. The preferred way to open a file is with the builtin open() function. Add a ‘U’ to mode to open the file for input with universal newline support. Any line ending in the input file will be seen as a ‘n’ in Python. Also, a file so opened gains the attribute ‘newlines’; the value for this attribute is one of None (no newline read yet), ‘r’, ‘n’, ‘rn’ or a tuple containing all the newline types seen.
‘U’ cannot be combined with ‘w’ or ‘+’ mode.
-
close
() → None or (perhaps) an integer. Close the file.¶ Sets data attribute .closed to True. A closed file cannot be used for further I/O operations. close() may be called more than once without error. Some kinds of file objects (for example, opened by popen()) may return an exit status upon closing.
-
closed
¶ True if the file is closed
-
encoding
¶ file encoding
-
errors
¶ Unicode error handler
-
fileno
() → integer "file descriptor".¶ This is needed for lower-level file interfaces, such os.read().
-
flush
() → None. Flush the internal I/O buffer.¶
-
isatty
() → true or false. True if the file is connected to a tty device.¶
-
mode
¶ file mode (‘r’, ‘U’, ‘w’, ‘a’, possibly with ‘b’ or ‘+’ added)
-
name
¶ file name
-
newlines
¶ end-of-line convention used in this file
-
next
¶
-
read
([size]) → read at most size bytes, returned as a string.¶ If the size argument is negative or omitted, read until EOF is reached. Notice that when in non-blocking mode, less data than what was requested may be returned, even if no size parameter was given.
-
readinto
() → Undocumented. Don't use this; it may go away.¶
-
readline
([size]) → next line from the file, as a string.¶ Retain newline. A non-negative size argument limits the maximum number of bytes to return (an incomplete line may be returned then). Return an empty string at EOF.
-
readlines
([size]) → list of strings, each a line from the file.¶ Call readline() repeatedly and return a list of the lines so read. The optional size argument, if given, is an approximate bound on the total number of bytes in the lines returned.
-
seek
(offset[, whence]) → None. Move to new file position.¶ Argument offset is a byte count. Optional argument whence defaults to 0 (offset from start of file, offset should be >= 0); other values are 1 (move relative to current position, positive or negative), and 2 (move relative to end of file, usually negative, although many platforms allow seeking beyond the end of a file). If the file is opened in text mode, only offsets returned by tell() are legal. Use of other offsets causes undefined behavior. Note that not all file objects are seekable.
-
softspace
¶ flag indicating that a space needs to be printed; used by print
-
tell
() → current file position, an integer (may be a long integer).¶
-
truncate
([size]) → None. Truncate the file to at most size bytes.¶ Size defaults to the current file position, as returned by tell().
-
write
(str) → None. Write string str to file.¶ Note that due to buffering, flush() or close() may be needed before the file on disk reflects the data written.
-
writelines
(sequence_of_strings) → None. Write the strings to the file.¶ Note that newlines are not added. The sequence can be any iterable object producing strings. This is equivalent to calling write() for each string.
-
xreadlines
() → returns self.¶ For backward compatibility. File objects now include the performance optimizations previously implemented in the xreadlines module.

open
()¶ Open file and return a stream. Raise IOError upon failure.
file is either a text or byte string giving the name (and the path if the file isn’t in the current working directory) of the file to be opened or an integer file descriptor of the file to be wrapped. (If a file descriptor is given, it is closed when the returned I/O object is closed, unless closefd is set to False.)
mode is an optional string that specifies the mode in which the file is opened. It defaults to ‘r’ which means open for reading in text mode. Other common values are ‘w’ for writing (truncating the file if it already exists), and ‘a’ for appending (which on some Unix systems, means that all writes append to the end of the file regardless of the current seek position). In text mode, if encoding is not specified the encoding used is platform dependent. (For reading and writing raw bytes use binary mode and leave encoding unspecified.) The available modes are:
Character Meaning ‘r’ open for reading (default) ‘w’ open for writing, truncating the file first ‘a’ open for writing, appending to the end of the file if it exists ‘b’ binary mode ‘t’ text mode (default) ‘+’ open a disk file for updating (reading and writing) ‘U’ universal newline mode (for backwards compatibility; unneeded for new code) The default mode is ‘rt’ (open for reading text). For binary random access, the mode ‘w+b’ opens and truncates the file to 0 bytes, while ‘r+b’ opens the file without truncation.
Python distinguishes between files opened in binary and text modes, even when the underlying operating system doesn’t. Files opened in binary mode (appending ‘b’ to the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when ‘t’ is appended to the mode argument), the contents of the file are returned as strings, the bytes having been first decoded using a platform-dependent encoding or using the specified encoding if given.
buffering is an optional integer used to set the buffering policy. Pass 0 to switch buffering off (only allowed in binary mode), 1 to select line buffering (only usable in text mode), and an integer > 1 to indicate the size of a fixed-size chunk buffer. When no buffering argument is given, the default buffering policy works as follows:
- Binary files are buffered in fixed-size chunks; the size of the buffer
is chosen using a heuristic trying to determine the underlying device’s
“block size” and falling back on
io.DEFAULT_BUFFER_SIZE
. On many systems, the buffer will typically be 4096 or 8192 bytes long. - “Interactive” text files (files for which isatty() returns True) use line buffering. Other text files use the policy described above for binary files.
encoding is the name of the encoding used to decode or encode the file. This should only be used in text mode. The default encoding is platform dependent, but any encoding supported by Python can be passed. See the codecs module for the list of supported encodings.
errors is an optional string that specifies how encoding errors are to be handled—this argument should not be used in binary mode. Pass ‘strict’ to raise a ValueError exception if there is an encoding error (the default of None has the same effect), or pass ‘ignore’ to ignore errors. (Note that ignoring encoding errors can lead to data loss.) See the documentation for codecs.register for a list of the permitted encoding error strings.
newline controls how universal newlines works (it only applies to text mode). It can be None, ‘’, ‘n’, ‘r’, and ‘rn’. It works as follows:
- On input, if newline is None, universal newlines mode is enabled. Lines in the input can end in ‘n’, ‘r’, or ‘rn’, and these are translated into ‘n’ before being returned to the caller. If it is ‘’, universal newline mode is enabled, but line endings are returned to the caller untranslated. If it has any of the other legal values, input lines are only terminated by the given string, and the line ending is returned to the caller untranslated.
- On output, if newline is None, any ‘n’ characters written are translated to the system default line separator, os.linesep. If newline is ‘’, no translation takes place. If newline is any of the other legal values, any ‘n’ characters written are translated to the given string.
If closefd is False, the underlying file descriptor will be kept open when the file is closed. This does not work when a file name is given and must be True in that case.
open() returns a file object whose type depends on the mode, and through which the standard file operations such as reading and writing are performed. When open() is used to open a file in a text mode (‘w’, ‘r’, ‘wt’, ‘rt’, etc.), it returns a TextIOWrapper. When used to open a file in a binary mode, the returned class varies: in read binary mode, it returns a BufferedReader; in write binary and append binary modes, it returns a BufferedWriter, and in read/write mode, it returns a BufferedRandom.
It is also possible to use a string or bytearray as a file for both reading and writing. For strings StringIO can be used like a file opened in a text mode, and for bytes a BytesIO can be used like a file opened in a binary mode.

property
(fget=None, fset=None, fdel=None, doc=None) → property attribute¶ fget is a function to be used for getting an attribute value, and likewise fset is a function for setting, and fdel a function for del’ing, an attribute. Typical use is to define a managed attribute x:

- def getx(self): return self._x def setx(self, value): self._x = value def delx(self): del self._x x = property(getx, setx, delx, “I’m the ‘x’ property.”)
Decorators make defining new properties or modifying existing ones easy:
- class C(object):
@property def x(self):
“I am the ‘x’ property.” return self._x@x.setter def x(self, value):
self._x = value@x.deleter def x(self):
del self._x
