How to get the function definition from an object?

Question

Suppose we have following code defined in tester.py

class Tester( object ):
    def method( self ):
        print 'I am a Tester'

and we have following defined in main.py

from tester import Tester
t = Tester()
#print definition of t

is there anyway we could get the definitions of a class/function from an object in a systematic way? or we have to parse the code and extract the code definition manually then save them into a string?

Answer 1

You can use the inspect module:

import inspect

class Tester( object ):
    def method( self ):
        print 'I am a Tester'

print inspect.getsource(Tester)

Output:

class Tester( object ):
    def method( self ):
        print 'I am a Tester'
