why do I keep getting "r" in results instead of "0" when I type r or R in input?
from random import randint
# Input
print("Rock: R Paper: P Scissors: S")
x = input("Please pick your choice: ")
y = randint(0,2)
if x.lower() == "r":
x == 0;
print("value entered ", x, "value generated ", y)
x == 0; is a boolean evaluating to False in your case. It tests if the value of x is equal to 0.
What you want is x = 0;
x is 'r', not that it matters :)
if x.lower() == "r" but not about x == 0; meaningThere are two problems:
x = 0 (assignment), not x == 0 (comparison).if x.lower() == "r":) is always going to be false, because your input has a trailing newline (that is, x will usually be something like "r\n". You want if x.strip().lower() == "r": instead.
raw_input is better.
raw_input is better because input runs eval on the user-supplied input and is a huge security risk (try typing __import__('os').system('rm -rf ~') at an input prompt, for example). raw_input will give you the trailing newline just the same. However, Python 3's input is Python 2's raw_input, renamed (Python 2's input was removed in Python 3).raw_input doesn't give the trailing \n. See the help(raw_input). It says Read a string from standard input. The trailing newline is stripped.
