Please any one can help me to solve the password validation solution in python??

Answer 1

Your code works fine if ininput "1$asdGhX" and it responds: "strong password". What problem do you have?

Answer 2

Where is your attempt?

Answer 3

import re
print("Enter the password")
password=input()
flag=0
while True:
if(len(password)<8):
flag=-1
break
elif not re.search("[a-z]",password):
flag=-1
break
elif not re.search("[A-Z]",password):
flag=-1
break
elif not re.search("[]0-9]",password):
flag=-1
break
elif not re.search("[_@$]",password):
flag=-1
break
elif re.search("\s",password):
flag=-1
break
else:
flag=0
print("strong password")
break
if flag==-1:
print("Weak password,try again with other constraints")

Answer 4

assign variables equal to len(re.findall(one variable should look for a-zA-Z characters, the next for 0-9 characters, and finally one for special characters, which you ought to be able to figure out how to do yourself). Lets call these a, b, and c. Now you've got three variables that equal the number of each type of character in your input string. Next you can make an if statement that says if a is greater than or equal to whatever it needs to be, AND b is greater than whatever it needs to be, (repeat this for c, connecting all three with 'and'), then print ("whatever you need it to say in the event that the password is valid"). Obviously you add an else to print whatever it needs to say for an invalid password.
