Been trying out some python as I learnt a bit in school and I've been trying to make a simple login system with password authentication.
The way I want it to work: get username and password, ask for password for authentication and if password is not correct then ask again until it gets the right one
this is my code so far:
#online auth
email = input('What is your email address?')
password = input('Enter a password')
passcheck = input('Please re-enter password for confimation')
while passcheck != password:
input('Please re-enter password for confirmation')
else: print("A confirmation code has been emailed to you")
When I run the program it asks for the email and username properly and then I get the confirmation question. If i enter the same password as the one i inputted in the first place it proceeds to the else statement. If i enter the wrong one it ends a never ending loop of reenter the password, even if i input the correct one.
I know that the while loop created an infinite loop but I cant find any good way to end it.
You could do something like
email = input('What is your email address?')
password_input = False
while not password_input or pass_check != password:
password = input('Enter a password')
pass_check = input('Please re-enter password for confimation')
password_input = True
print("A confirmation code has been emailed to you")
Just solved with the help of my friend:
#online auth
email = input('What is your email address?')
password = input('Enter a password')
passcheck = input('Please re-enter password for confimation')
while passcheck != password:
passcheck = input('Please re-enter password for confirmation')
else: print("A confirmation code has been emailed to you")
a good way to end a loop is to either use a for, or a counter variable
for index in range(0,5):
password = input('Enter a password')
pass_check = input('Please re-enter password for confimation')
if pass_check == password :
print("A confirmation code has been emailed to you")
index=65532
else :
print("The passwords do not match, try again.")
if index != 65532 :
print("too many attempts, if you want to retry, please restart the program")
note : the 65532 is not special, it's just out of range, so you exit the for.
