We use the getsource() method of inspect module to get the source code of the function.
Returns 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.
If the function is compiled from a string, stream or imported from a compiled file, then you cannot retrieve its source code.
We import the inspect module and retrieve the source code for given script as follows
#baz.py import inspect class foo: def bar(): print 'Hello' print(inspect.getsource(foo))
C:/Users/TutorialsPoint1/~.py class foo: def bar(): print 'Hello'
