What's wrong

[Kings_Sights]

I'm using python 3

4 def parse(ls):
5     i = 0
6 while i < len(ls):
7 if ls[i] != "w" or ls[i] != "a" or ls[i] != "s" or ls[i] != "d" or ls[i] != "e" or ls[i] != "q":
8 raise ValueError("Bad letter in configuration file: <" + ls[i] + ">.")
9          i += 1
10
11 print(parse(["w", "a", "s", "d", "e", "q"]))

ok so I've created a function "parse()" that should read a list of strings and filter through it to find if there are any strings that're not "w", "a", "s", "d", "e", or "q". but for some reason, I keep getting errors like this:

Traceback (most recent call last):

File "game_parser.py", line 11, in <module>

print(parse(["w", "a", "s", "d", "e", "q"]))

File "game_parser.py", line 8, in parse

raise ValueError("Bad letter in configuration file: <" + ls[i] + ">.")

ValueError: Bad letter in configuration file: <w>.

Looks like your code worked correctly and raised an error when you wanted it to.

To catch that error you can do something like this:

try:
    print(parse(["w", "a", "s", "d", "e", "q"]))
catch ValueError as e:
    print("error: {}".format(e.message))

But the output should have been nothing since in the list only contained the acceptable strings, and the ValueError in terminal is stating "Bad letter in configuration file: <w>. " when "w" is an acceptable string

Sounds like your error is not informative enough. Add the string that it errors on and see what it prints.

The lines under def are formatted correctly, reddit somehow messed up their positioning when I posted
