Import file1 inside file2:
To import all variables from file1 without flooding file2's namespace, use:
import file1
#now use file1.x1, file2.x2, ... to access those variables
To import all variables from file1 to file2's 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.

March 26, 2022Importing a variable from another python file imports everything?
When you import a file, that file gets run. The only difference between import file and from file import name, is that you can then access name directly, as opposed to file.name. For this reason it is important that imported files check to see if __name__ == ' __main__', before executing any code, like this: names = ['Jack', 'Daniels', 'Johnnie', 'Walker'] print('i am running') # prints on import def main(): # some code here to run when the file is run directly and not imported if __name__ == '__main__': main() More on reddit.com

Importing Variables From Another File | by George | Medium
November 17, 2020 - If we want to choose specific variables to import, we can do so by indicating the variable names (that are in the file we want to import from): One thing to note is that if you have a defined variable with a name that’s the same as the variable you want to import, it will be overwritten after you import the variable. Like usual, Python will run from top to bottom, so the value that the variable takes depends on the order at which you define the variable and import a variable with the same name.

Importing variables from other files in Python | by aneesh joshi | codeburst
June 30, 2017 - └> python B.py the value of __name__ in A is A Imported value of a is 0 value of __name__ in B is __main__ The takeaway is that when A is called from B, the whole script of A is executed and the value of __name__ is 'A’ inside the A script. Because __name__ is 'A' , the last print statement in A is not executed. Since we ran the B.py file as a script, the value of __name__ is '__main__'

For example, I want to import all variables from file work.py to use in my current file. The code in work.py is written inside def main():
If I use-> from work import *
It seems to import only variables outside function “main”. I cannot access to the variables created inside function “main”. How to access to variables inside function main?

The whole purpose of a function is to enclose local variables and not expose them to the outside. If you want a function to have some value from main, you pass that value as an argument when you call that function. def main(): v = 1 otherfunc(v) def otherfunc(v): #now otherfunc has access to v's value print(v)

SOL if you can't edit work.py If you can edit it, you can either have it return values once run, redefine every variable from "var =" to "main.var =" or add "global var" for every variable.

Importing needs to execute (run) the full file of imported code in order to determine what the imported values should be. If you have a script file with some defining variables and functions, and then some code using those, the “using”/calling code should be in an if __name__ == '__main__': block at the end of the file so it only gets executed when the file is run as a script, which means importing only runs the code before that.

The set up is like this:
Dir:
| Folder 1:
| | FileDestination
| Folder 2:
| | SubFolder:
| | | FileWithVariable
Ive tried to do:
import Folder 2.SubFolder.FileWithVariable as Var
This doesn't work and Im not sure why.
Side note, how would I go about typing a folder with a space in its name like 'Folder 2'?
Thanks in advance, I've been thrown into coding in python for research and some things have been a struggle!

Importlib & Namespaces Basically, your files are not a package namespace, so any imports using the regular import system will not work unless it’s available on the interpreters path. You can use importlib to import directly from an absolute path, but you can also just initialize your directories as package namespaces, using __init__.py files.

Top answer 1 of 3

Everything you've done is right except when using the variables.
In your main_file.py file:
if(variables.flag == 0) :
variables.j = variables.j + 1
(Or)
Use the following header :
from variables import *
(Or)
from variables import flag, j
Replace all the references of flag and j (or any other variable you want to use from that file) with the prefix 'variables.'
Since this is just a copy of the variable, the values in the variables.py won't get affected if you modify them in main_file.py

You can either use
import variables
and then access the vairables like this:
variables.flag
variables.j
or you can use:
from variables import flag, j
and then access the vaiables by just their name.
Important:
Please note that in the second case, you will be working with a copy of the variables, and modifying them in one module has no effect on the variables in the other module!

How to Import and Change Variables from Another File in Python: A Beginner's Guide — pythontutorials.net
Mutable variables (lists, dicts) modified in the importing file will change the original module’s data. Immutable variables (ints, strs) require importing the entire module to update the original value. Avoid from module import * and circular imports to keep your code maintainable. With these concepts, you’ll confidently manage variables across modules and build cleaner, more organized Python projects.
