Elif gives "ParseError: bad input" on trinket.io

I'm making a simple Python Rock Paper Scissors game for a school project. I'm new to Python but I'm getting the error

ParseError: bad input on line 12 in main.py

Here is my code:

import random


choice = input("Welcome to rock paper scissors! You go first.")
choice = choice.upper()
a = [1, 2, 3]

b = random.choice(a)

if b == 1:
print("My choice: ROCK")
elif b == 2:
  print("My choice: PAPER")
    elif b = 3:
      print("My choice: SCISSORS")



print("Your choice: " + choice)


if choice == b:

 print "Draw. Play again!"

So it's the Elif statements that are giving me trouble, but I don't see how they could possibly be wrong, I've looked everywhere.

Solution

  • Your indentation is wrong: the elif must be at the same level. Besides, you wrote elif b = 3, but it should be elif b == 3.

    if b == 1:
    print("My choice: ROCK")
elif b == 2:
    print("My choice: PAPER")
elif b == 3:
    print("My choice: SCISSORS")

    Note that the code as you posted raises an IdentationError in a Python 3 interpreter.
