Is there a way to print the definition of a function in python

Question

I was wondering if there is a way to print what the funciton definition?

so if I want to do something like:

def hello():
    print 'hello'

some_function_to_show_definition(hello())

and the output should be:

print 'hello'

Just messing around in python and I was just wondering :)

you might want to check [https://github.com/ipython/ipython/blob/313df3800a05f4ef72fb7bf4509ed699926cb1b2/IPython/core/oinspect.py] — , May 03 '14 at 01:48

inspect is the way to go:

In [8]: def foo():
   ...:     print 'hello'
   ...:     

In [9]: import inspect

In [10]: inspect.getsourcelines(foo)
Out[10]: ([u'def foo():\n', u"    print 'hello'\n"], 1)

You just beat me to it! Just a note, this does not work in `CPython` interactive mode. – ubomb May 02 '14 at 22:40
Yep, it's probably not a good idea if a program relies on such kind of low level introspection. – Grapsus May 02 '14 at 22:42
