Python: Raw_Input inside an if statement?

Question

I'm starting out at python. I keep getting an error when I put a new raw_input inside an if statement. If the input they answered is incorrect I want to give them another chance to enter more input, is there another way to do this?

Heres the Code

attraction = {
    'approach' : "words",
    'introduction' : "words",
    'qualification' : "words",
    'rapport' : "words"
}

answer = raw_input("Pick from these approaches: introduction, qualification, or rapport:")

if answer != "approach" and answer != "introduction" and answer != "qualification" and answer != "rapport":
    new_answer = raw_input("You didn't choose one of the choices, type in the choice you want again:")
if new_answer != "approach" and answer != "introduction" and answer != "qualification" and answer != "rapport":
    print "That was your last chance buddy"
else:
    print attraction[answer]

put the raw input in a while loop. Use break when you have an answer — demented hedgehog

I know this is not a related question, but, may I ask why did you start out learning Python 2.7? Why not Python 3? — yeyo

Not related to your question: it's easier to write: if answer not in ("approach", "introduction", "qualification", "rapport"): — Nir Alfasi

I think you should use or expression instead of `and' because single input can't be of 3 different type. — Tanveer Alam

You don't need to make a new variable new_answer when you're asking them the second time, you can just set answer to a new value:

answer = raw_input("You didn't choose one of the choices, type in the choice you want again:")

And replace new_answer with answer elsewhere in your program.

I would do the program like this, using the .keys() method:

attraction = {
    'approach' : "words",
    'introduction' : "words",
    'qualification' : "words",
    'rapport' : "words"
}

answer = raw_input("Pick from these approaches: introduction, qualification, or rapport:")

while not answer in attraction.keys():
    answer = raw_input("You didn't choose one of the choices, type in the choice you want again:")

print attraction[answer]

you don't even need to use .keys(). By definition a dictionary iterates over it's keys - so you can simply use while not answer in attraction:

And that's what I get for not actually running the code in my answer.

@PeterWood Note that the in-loop raw_inputs have a different prompt than the initial one.

You can simply write:

while True:
    answer = raw_input("Pick from these approaches: introduction, qualification, or rapport:")
    if answer == "approach" or answer == "introduction" or answer == "qualification" or answer == "rapport":
        break
