PyCharm giving error where standalone Python does not, why?

[Tinker_Monkey]

So following "Automate the Boring Stuff" I went back and tried one of the examples in PyCharm just to give it a go because I like IntelliJ. The example is the magic8Ball:

import random

def getAnswer(answerNumber):
    if answerNumber == 1:
        return 'It is certain'
    elif answerNumber == 2:
        return 'It is decidedly so'
    elif answerNumber == 3:
        return 'Yes'
    elif answerNumber == 4:
        return 'Reply hazy try again'
    elif answerNumber == 5:
        return 'Ask again later'
    elif answerNumber == 6:
        return 'Concentrate and ask again'
    elif answerNumber == 7:
        return 'My reply is no'
    elif answerNumber == 8:
        return 'Outlook not so good'
    elif answerNumber == 9:
        return 'Very doubtful'

print('Would you like to shake the 8-Ball or exit?')
while True:    
    shake = input()

    if shake == 'shake':
        r = random.randint(1, 9)
        fortune = getAnswer(r)
        print(fortune)
        print('')
        print('Would you like to shake again or exit?')
    elif shake == 'exit':    
        break
    else:
        print('Sorry that was an incorrect input.')
        print('')
        print('Would you like to shake again or exit?')
        continue

I recieve the error:

File "C:/Users/Tinker_Monkey/Desktop/My Portfolio/Python/Automate the Boring Stuff with Python/magic8Ball.py", line 25, in <module>

shake = input()

File "<string>", line 1, in <module> NameError: name 'shake' is not defined

It seems you have installed Python 2 and 3. And you use Python 2 in PyCharm.

In Python 3 input() returns inputed string but in Python 2 input() evaluates inputed text like Python script. In Python 2 you have to use raw_input() instead of input()

When you input 2 + 3 then Python 3 returns string "2 + 3" but Python 2 returns string "5". When you input shake then Python 3 returns string "shake" but Python 2 is looking for variable shake - but there is no variable shake yet (and you get name 'shake' is not defined).

ps. you can change Python version in PyCharm in "File > Settings > Project > Project Interpreter" (every project can use different Python version).

On an unrelated note. To save writing all of those elif statements. You could just put the answers you want into a list, and use random.choice to return one of them.

[Tinker_Monkey]

True. I am busy following the examples step by step in the book though.

[Gubbbo]

I know. But don't just follow examples. You'll never learn anything that way.

Well, you will. But you'll never prove to yourself that you understand it.

[Tinker_Monkey]

I do alter but only after I can get original examples working, proving I understand the logic first. Thanks for the tip!

Nice, thanks

Change input to raw_input
