Python - Why is the function not working when reading from file? [closed]

Question

This is the code i have used

file

Answer 1

I think you meant to read all the lines from the file and look at the last one. Like this:

try:
    lines = myfile.readlines()
    GetTopic = lines[-1].strip()
    ...

Your code read one line into lines and lines[-1] was a single character and GetTopic = print(lines[-1]) meant that GetTopic was None and so not equal to any of your literal strings.

Answer 2

• readline() returns a string - the first line of the document.
• readlines() returns an array, which is probably what you're expecting.
  • I prefer to use lines = [x.strip() for x in myfile.readlines()]
• The result of assigning a print() is always None. Python isn't the command line.
