Python NameError from contents of a variable

Question

I\'ve been making a mod for the Raspberry Pi version of Minecraft and I\'m getting a very frustrating error every time I enter one of the commands in my program. Here\'s my code

Answer 1

when you use the input() to input the newBlock , the parser regards the newBlock as the variable instead of string. so you need to use raw_input

see the ref of the input()

def input(prompt):
    return (eval(raw_input(prompt)))
