Python Expected type 'Sized', got 'int' instead

[skifli]

Hi. I'm coding a hangman game in Python & I've been getting an error that I can't figure out how to get rid off. Basically, after I take the user's letter, I create a counter that goes from 0 to the length of the word. However, since Python uses the number 0 first, instead of 1, I have to do the user's guess - 1. If I don't it'll give an index out of range error. But when I run it it gives me an error saying:

'
Traceback (most recent call last):
File "C:\Users\Administrator\Documents\Coding\Games\Hangman.py", line 46, in <module>
for counter in range(len(0, user_guess - 1)):
TypeError: unsupported operand type(s) for -: 'str' and 'int'
'
Any help would be appreciated. Here is the part of the code the error is in:
[CODE lang="python" title="Code" highlight="4"]user_guess = input("Enter a letter: ")

for counter in range(len(user_guess - 1)):
if user_guess == word[counter]:
user_word_guesses[counter] = user_guess[/CODE]

I think that python is treating the user_guess as a string, so when you try to do the subtraction it fails because you can't subtract a number from a string. Try casting the string as an int: https://www.w3schools.com/python/python_casting.asp

I'm sorry, I think you misunderstood. The user's input is meant to be a string, not an integer. The ' -1 ' part is not meant to be applied onto the string, but rather the length of the string in characters, which is got by doing:[CODE lang="python" title="COde" highlight="1"]len(user_input) # len() means get length[/CODE]

Yeah, but you are doing len(user_guess - 1), which I would think should instead be len(user_guess) - 1 right? Just taking a guess as I don't code in Python, hopefully it helps.
