How to call a function stored in another file from a Python program?

Question

If I have a text file that contains a python function definition, how can I make the function call from another Python program. Ps: The function will be defined in the Pytho

Answer 1

You are looking for the exec keyword.

>>> mycode = 'print "hello world"'
>>> exec mycode
Hello world

So if you read your text file as text (assuming that it only contains the function) like:

test.txt:

def a():
    print "a()"

test.py:

mycode = open('test.txt').read()
exec mycode # this will execute the code in your textfile, thus define the a() function
a() # now you can call the function from your python file

You may want to look at the compile statement too: here.
