Call a function from another file in Python

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

You should have the file at the same location as that of the Python files you are trying to import. Also 'from file import function' is enough.

Answer 2

in my case i named my file helper.scrap.py and couldn't make it work until i changed to helper.py

Answer 3

You can do this in 2 ways. First is just to import the specific function you want from file.py. To do this use

from file import function

Another way is to import the entire file

import file as fl

Then you can call any function inside file.py using

fl.function(a,b)

Answer 4

First save the file in .py format (for example, my_example.py). And if that file have functions,

def xyz():

        --------

        --------

def abc():

        --------

        --------

In the calling function you just have to type the below lines.

file_name: my_example2.py

============================

import my_example.py


a = my_example.xyz()

b = my_example.abc()

============================

Answer 5

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.

Came across the same feature but I had to do the below to make it work.

If you are seeing 'ModuleNotFoundError: No module named', you probably need the dot(.) in front of the filename as below;

from .file import funtion
