python – Importing variables from another file?

from file1 import *  

will import all objects and methods in file1

Import file1 inside file2:

To import all variables from file1 without flooding file2s namespace, use:

import file1

#now use file1.x1, file2.x2, ... to access those variables

To import all variables from file1 to file2s namespace( not recommended):

from file1 import *
#now use x1, x2..

From the docs:

While it is valid to use from module import * at module level it is
usually a bad idea. For one, this loses an important property Python
otherwise has — you can know where each toplevel name is defined by a
simple “search” function in your favourite editor. You also open
yourself to trouble in the future, if some module grows additional
functions or classes.

Best to import x1 and x2 explicitly:

from file1 import x1, x2

This allows you to avoid unnecessary namespace conflicts with variables and functions from file1 while working in file2.

But if you really want, you can import all the variables:

from file1 import *
