I have a python file named `main.py` which looks like this:

```
print('hello world')

```

I also have a `tkinkter_run.py` file which looks like this:

```
import sys
import os
from tkinter import *
import main

window=Tk()

window.title("Running Python Script")
window.geometry('550x200')

def run():
    os.system('main.py')

btn = Button(window, text="Run your Code!", bg="blue", fg="white",command=run)
btn.grid(column=0, row=0)

window.mainloop()

```

When I run my `tkinker_run.py` file I do get a window with a `Run your Code!` button, however when I click that button and look the my terminal in Visual Code I get the following error:

```
Hello World
'main.py' is not recognized as an internal or external command,
operable program or batch file.

```

So it seems that `Hello World` is printed before I even click the `Run your Code!` button. I dont understand what the problem is....
