Answers to this question couldn't clear the problems
I tried this but it doesn't worked
N = [1,2,3,4,5,6,7,8,9,0]
A = ['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z']
S = ['!','@','#','$','%','~','`','^','&','*','(',')','_','+','=','-']
pasw = input('Password: ')
if any((word in pasw for word in N,A,S)):
print ('OK')
else:
print ('TRY LATER')
The best way is with a regex as suggested, but that is a whole new world if you don't know what one is. I suggest you read up.
But using code you understand it can be done:
pasw='PAssword1!!'
S = ['!','@','#','$','%','~','`','^','&','*','(',')','_','+','=','-']
upper,lower,number,special = 0,0,0,0
for n in pasw:
if n.islower():
lower=1
if n.isnumeric():
number=1
if n.isupper():
upper+=1
if n in S:
special+=1
if len(pasw) >= 6 and len(pasw) <= 12 and lower > 0 and number > 0 and special > 1 and upper > 1:
print('OK')
else:
print('TRY LATER')
