zloy xaker [14]

Answer:

def enterNewPassword():

 while True:

   password = input("Enter password: ")

   has_digit = False

   for i in password:

     if i.isdigit():

       has_digit = True

       break

   

   if not has_digit or (len(password) < 8 or len(password) > 15):

     if len(password) < 8 or len(password) > 15:

       print("The password length must be between 8 and 15!")

     if not has_digit:

       print("The password must include at least one digit!")

   else:

     return password

print(enterNewPassword())

Explanation:

*The code is in Python.

Create a function named enterNewPassword that takes no parameter

Create an indefinite while loop. Inside the loop, ask the user to enter the password. Initialize the has_digit as False, this will be used to check if password contains a digit or not. Create a for loop, that that iterates through the password, if one character is digit, set the has_digit as True and stop the loop (Use isdigit() to check if the character is digit or not).

After the for loop, check if has_digit is false or the length of the password is not between 8 and 15. If the length of the password is not between 8 and 15, print the error. If has_digit is false, again print the error.

Otherwise, password met the requirements and return the password

Call the enterNewPassword() function and print the result
