- currentframe = _getframe(...)
- _getframe([depth]) -> frameobject
Return a frame object from the call stack. If optional integer depth is
given, return the frame object that many calls below the top of the stack.
If that is deeper than the call stack, ValueError is raised. The default
for depth is zero, returning the frame at the top of the call stack.
This function should be used for internal and specialized
purposes only.
- findsource(object)
- Return the entire source file and starting line number for an object.
The argument may be a module, class, method, function, traceback, frame,
or code object. The source code is returned as a list of all the lines
in the file and the line number indexes a line in that list. An IOError
is raised if the source code cannot be retrieved.
- formatargspec(args, varargs=None, varkw=None, defaults=None, formatarg=<type 'str'>, formatvarargs=<function <lambda> at 0xd5e488>, formatvarkw=<function <lambda> at 0xd5e500>, formatvalue=<function <lambda> at 0xd5e578>, join=<function joinseq at 0xd5e398>)
- Format an argument spec from the 4 values returned by getargspec.
The first four arguments are (args, varargs, varkw, defaults). The
other four arguments are the corresponding optional formatting functions
that are called to turn names and values into strings. The ninth
argument is an optional function to format the sequence of arguments.
- formatargvalues(args, varargs, varkw, locals, formatarg=<type 'str'>, formatvarargs=<function <lambda> at 0xd5e668>, formatvarkw=<function <lambda> at 0xd5e6e0>, formatvalue=<function <lambda> at 0xd5e758>, join=<function joinseq at 0xd5e398>)
- Format an argument spec from the 4 values returned by getargvalues.
The first four arguments are (args, varargs, varkw, locals). The
next four arguments are the corresponding optional formatting functions
that are called to turn names and values into strings. The ninth
argument is an optional function to format the sequence of arguments.
- getabsfile(object)
- Return an absolute path to the source or compiled file for an object.
The idea is for each object to have a unique origin, so this routine
normalizes the result as much as possible.
- getargs(co)
- Get information about the arguments accepted by a code object.
Three things are returned: (args, varargs, varkw), where 'args' is
a list of argument names (possibly containing nested lists), and
'varargs' and 'varkw' are the names of the * and ** arguments or None.
- getargspec(func)
- Get the names and default values of a function's arguments.
A tuple of four things is returned: (args, varargs, varkw, defaults).
'args' is a list of the argument names (it may contain nested lists).
'varargs' and 'varkw' are the names of the * and ** arguments or None.
'defaults' is an n-tuple of the default values of the last n arguments.
- getargvalues(frame)
- Get information about arguments passed into a particular frame.
A tuple of four things is returned: (args, varargs, varkw, locals).
'args' is a list of the argument names (it may contain nested lists).
'varargs' and 'varkw' are the names of the * and ** arguments or None.
'locals' is the locals dictionary of the given frame.
- getblock(lines)
- Extract the block of code at the top of the given list of lines.
- getclasstree(classes, unique=0)
- Arrange the given list of classes into a hierarchy of nested lists.
Where a nested list appears, it contains classes derived from the class
whose entry immediately precedes the list. Each entry is a 2-tuple
containing a class and a tuple of its base classes. If the 'unique'
argument is true, exactly one entry appears in the returned structure
for each class in the given list. Otherwise, classes using multiple
inheritance and their descendants will appear multiple times.
- getcomments(object)
- Get lines of comments immediately preceding an object's source code.
- getdoc(object)
- Get the documentation string for an object.
All tabs are expanded to spaces. To clean up docstrings that are
indented to line up with blocks of code, any whitespace than can be
uniformly removed from the second line onwards is removed.
- getfile(object)
- Work out which source or compiled file an object was defined in.
- getframeinfo(frame, context=1)
- Get information about a frame or traceback object.
A tuple of five things is returned: the filename, the line number of
the current line, the function name, a list of lines of context from
the source code, and the index of the current line within that list.
The optional second argument specifies the number of lines of context
to return, which are centered around the current line.
- getinnerframes(tb, context=1)
- Get a list of records for a traceback's frame and all lower frames.
Each record contains a frame object, filename, line number, function
name, a list of lines of context, and index within the context.
- getlineno(frame)
- Get the line number from a frame object, allowing for optimization.
- getmembers(object, predicate=None)
- Return all members of an object as (name, value) pairs sorted by name.
Optionally, only return members that satisfy a given predicate.
- getmodule(object)
- Return the module an object was defined in, or None if not found.
- getmoduleinfo(path)
- Get the module name, suffix, mode, and module type for a given file.
- getmodulename(path)
- Return the module name for a given file, or None.
- getouterframes(frame, context=1)
- Get a list of records for a frame and all higher (calling) frames.
Each record contains a frame object, filename, line number, function
name, a list of lines of context, and index within the context.
- getsource(object)
- Return the text of the source code for an object.
The argument may be a module, class, method, function, traceback, frame,
or code object. The source code is returned as a single string. An
IOError is raised if the source code cannot be retrieved.
- getsourcefile(object)
- Return the Python source file an object was defined in, if it exists.
- getsourcelines(object)
- Return a list of source lines and starting line number for an object.
The argument may be a module, class, method, function, traceback, frame,
or code object. The source code is returned as a list of the lines
corresponding to the object and the line number indicates where in the
original source file the first line of code was found. An IOError is
raised if the source code cannot be retrieved.
