"open" method in Python not converting string to integer-CodePudding

Weird things happen when I try to run this piece of code:

        with open("snake score.txt", mode="r") as f:
            self.high_score = int(f.read())

The error I get is:

  File "C:\Users\Lidor\PycharmProjects\100DaysOfCode\snake.py", line 77, in __init__
    self.high_score = int(f.read())
ValueError: invalid literal for int() with base 10: ''

The output I get is '0'

CodePudding user response：

Make sure you have no extra spaces in your string.

self.high_score = int(f.read().strip())

Python can't read the file name and do stuff with the file if it has an empty whitespace/space character " " in it. Using the strip() method, you remove the whitespaces from within the code and proceed.
