Is there a way so that a statement doesn't run at the start of a program?

I am making an MS-DOS operating system in Python, and I want the user to select an application to run.

print("""
[1] Open notepad
[2] Open file explorer
[3] Configure BIOS
[4] Exit OS safely
""")
select = input("[?]: ")
if select == '1':
    execfile('edit.py')
if select == '2':
    execfile('file.py')

But edit.py runs first.

I tried assigning select to 0 at the start of the program, expecting select to not be anything (hence, no app runs), but it didn't work.

select = '0'
...
print("""
[1] Open notepad
[2] Open file explorer
[3] Configure BIOS
[4] Exit OS safely
""")
select = input("[?]: ")
if select == '1':
    os.startfile('edit.py')
if select == '2':
    os.startfile('file.py')

What do you mean by ``edit.py runs first`` ? – Cubix48 Feb 21 '22 at 17:07

Do you have an `import edit` statement somewhere? – Ben Grossmann Feb 21 '22 at 17:08
yes, I've written import edit at the start of the program – Epicyerik GS and ENTMNT Feb 21 '22 at 17:11
Cubix48 edit.py runs at the start of the program and everything runs after it. – Epicyerik GS and ENTMNT Feb 21 '22 at 17:12
When you `import` something, it runs the script. You'll need to wrap your code you don't wish to run in a function or `if __name__ == '__main__':` block. – Axe319 Feb 21 '22 at 17:14
