Why is my python file not working outside of VS Code?

Question

I’m trying to run a python script as an executable and when I open it, the first input comes up and it just closes after any input. I tried running the .exe file, the .py file and both have this result.
Here’s a short version of the code:

print("Example Text")
start = int(input("""
To start, press 1.
To leave, press 2.""")
a = open("FilesDocumentsFull.txt")
b = open("FilesDocumentsPart 1.txt")
c = open("FilesDocumentsPart 2.txt")
d = open("FilesDocumentsPart 3.txt")
while True:
    print("""Which part do you want to view?
    1. Part One
    2. Part Two
    3. Part Three
    4. All of it
""")
    segment = int(input())
    if segment == 1:
        print(b.read())
    elif segment == 2:
        print(b.read())
    elif segment == 3:
        print(c.read())

I tried removing the while True: statement at the start, putting only the if segment == part in a loop, I reinstalled the .exe file with the new code and it didn’t work. It’s supposed to just loop through asking what file to print and printing the contents of that file.

I think this happens because you don’t have the files you want to open in your local working directory.

I adapted the code a bit to show this to you. When you double click a python script / an exe file in windows, it opens a terminal only until the program termiantes. Therefore you probably don’t see the error message.

With the adapted code you should see a file not found exception pop up:

import os


while True:
    try:

        start = int(input(""" To start, press 1.  To leave, press 2."""))
        a = open("FilesDocumentsFull.txt")
        b = open("FilesDocumentsPart 1.txt")
        c = open("FilesDocumentsPart 2.txt")
        d = open("FilesDocumentsPart 3.txt")
        print("""Which part do you want to view?
        1. Part One
        2. Part Two
        3. Part Three
        4. All of it
        """)

                
        segment = int(input())
        if segment == 1:
            print(b.read())
        elif segment == 2:
            print(b.read())
        elif segment == 3:
            print(c.read())

    except Exception as e:
            print(f'an exception occurred: {e}')
            
            print(os.getcwd())

The current working directory is printed when the exception occurs.

You can fix your problem by replacing the relative paths (e.g., FilesDocumentsFull.txt) by absolute paths (e.g., C:Users...FilesDocumentsFull.txt).

When you are not executing your code inside your IDE, you should execute it in a terminal emulator (e.g. powershell), by starting powershell, navigating to the directory that contains your python script, and typing [path/to/python3] [filename.py], e.g. python3 test.py.
