I am trying to create a game of rock, paper, scissors. However, when I try to .format a string inside of an input function using a slice I am getting the following:Choose Rock, Sciss or Scissors:
I am using the following script:
options = ['rock', 'paper', 'scissors']
def rock_paper_scissors():
x = ''
for option in options:
if x == '':
x += option.title()
else:
x += ', ' + option.title()
player = input('Choose {} or {}:'.format(x[0:11], x[-8:]))
It's not the slicing that's going wrong, it's the string construction. You should indent the else: block a bit more. For reference, try print()-ing x before your input command.
Python for loops can have an else: clause. These are executed unless a loop is terminated by break or return. Therefore, your loop only did something on the first iteration while x was still an empty string, and then the else clause would modify your string with the option still bound from the last iteration of your loop.
Perhaps I'm a bit to used to Code Review, but I'd suggest doing the construction differently, more like this:
player_move = input(f"Choose {', '.join(options[:-1])} or {options[-1]}")
Do note, though, that this will only work for a 3+ length for options. To get a fitting string for less options requires a more... elegant construction.
