How to import file with variables?

Question

In Python (2.7), I'd like to create several variables in a file. Then use those variables in other files. There aren't any classes or function. Just accessing those variables from different files.

How is that done for the file containing variables, which might look like this?

variables.py

a = 1
b = 2
c = 3

Then in a file that wants to use those variables?

file1.py

print a + b

Another way is to import file than use filename to access variables:

import variables

print variables.a + variables.b

This is a better implementation - it keeps the naming clear. – asongtoruin Feb 13 '17 at 15:17
This technique seems to handle the pylint error I commented on from the first answer. – 4thSpace Feb 13 '17 at 18:15
It's better to use this import while your file only contains variables. – metmirr Feb 13 '17 at 18:18
Definitely better. Answered my way since exactly asked what he needed. :) – Bipul Jain Feb 13 '17 at 18:23

If those are in proper python format i.e. the way you have mentioned above

In your file1.py You can just do this.

from variables import *

print a + b

Why does pylint keep complaining "E0602:Undefined variable 'myvar1'"? – 4thSpace Feb 13 '17 at 18:14
What's your filename for keeping your variables? – Bipul Jain Feb 13 '17 at 18:15
Same as in the OP: variables.py. – 4thSpace Feb 13 '17 at 18:35

You can use import to import your work from that file to the next, like so:

from variables import *

print a + b
