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

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

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!

Yep! That's what happens when I rush!

Ikr, so much pressure to get your answer at the top :D

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>")

you can use execfile(filepath) to get run
