Call a function from another file?

Question

Set_up: I have a .py file for each function I need to use in a program.

In this program, I need to call the function from the external files.

I've tried:

from file.py import function(a,b) 

But I get the error:

ImportError: No module named 'file.py'; file is not a package

How do I fix this problem?

Answer 1

There isn't any need to add file.py while importing. Just write from file import function, and then call the function using function(a, b). The reason why this may not work, is because file is one of Python's core modules, so I suggest you change the name of your file.

Note that if you're trying to import functions from a.py to a file called b.py, you will need to make sure that a.py and b.py are in the same directory.

Answer 2

First of all you do not need a .py.

If you have a file a.py and inside you have some functions:

def b():   # Something   return 1  def c():   # Something   return 2 

And you want to import them in z.py you have to write

from a import b, c
