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)))

Answer 2

You're using input where you need to be using raw_input. input evaluates the string that it's passed. raw_input gives you a string, which is what you want.

Note that this only applies in Python 2. In Python 3, raw_input is no longer available and input is the equivalent of Python 2's raw_input. In Python 2, input is equivalent to eval(raw_input)
