how to ask what something is (input) then if they get it wrong it'll ask them again (while loop)

Question

I'm doing a GCSE in computing and starting a new code for fun and I'm having trouble like a noob. I am making a code asking them what the password is and if they get it wrong it'll ask again until the requirements are met, I have looked on the internet and it gave me a countdown on all of the websites I checked. this is my code so far...

password = 1234
passinput = (input("what is your password? "))

I have tried several things such as...

while True:

and

while False:

but I don't understand how to use them properly. I have learned it in class, but it's an easy thing to forget. I want the code to keep on asking the user until they input "1234" (the password)

please help.

The simple answer is:

while True:
    answer = input('password?')
    if answer == password:
        break

Fro more complex needs (or a better understanding of the options), see Asking the user for input until they give a valid response.

it keeps looping instead of breaking. – Chimpeus Styx Jul 04 '15 at 17:33
@ChimpeusStyx: try `password = "1234"` – Ethan Furman Jul 04 '15 at 18:27

More simple way

password = 1234
while int(input()) != password: pass

this code just loops even if I put the password in – Chimpeus Styx Jul 04 '15 at 18:16
@ChimpeusStyx No, this loops only until you enter the correct password, i.e. 1234 here. – Shreevardhan Jul 05 '15 at 01:46

The short way:

while True:
    if input("what's the password? ") == "1234":
        break

Or even shorter:

while input("what's the password? ") != "1234":
    pass

Or if you'd insist on a one- liner:

while input("what's the password? ") != "1234": pass
