How do you run a python file from another python file?

Question

Im trying to run another file from my tkinter login system but i cant find the way to do it

Ive tried import file

if (p == '123') and (u == 'test'):
    import correct

Im trying to run the file when those are true

Don't "run the file". Import a function from it at at the beginning of your code, and call that function inside that `if` statement (though what you wrote should technically work if that file contains global code, so I guess you've got some other problem in your code). — goodvibration, May 28 '19 at 06:58

I agree with the first answer, if your point is to use functions / classes / variables... from another file. But still if you REALLY want to run your module you can with `os.system('py your_module.py')` — Nqsir, May 28 '19 at 07:07

One hacky way to do it, if you really have to is this:

with open("correct.py", "r") as f:
    exec(f.read())

But you should avoid doing this if possible. Normally it is better import the file and run a function from it.

Yes, I accidentally pressed submit before I'd finished – fixed it now! – LeopardShark May 28 '19 at 07:06

If you want to run a file separately without importing it do this.

from os import system
#system calls a command from terminal
system("python <path to python file>")
