Homework answers / question archive / Python program to determine whether a password meets all the requirements for a secure password
Python program to determine whether a password meets all the requirements for a secure password. Your program should prompt the user for the candidate password and output either that the password is valid or the reason it is invalid. To be valid the length of the password must greater than some minimum length but less than some maximum. It must not include the substring "umgc" in any combination of upper or lower case letters. Finally, it must contain the # symbol is some position other than the first or last character. You should decide on the minimum and maximum allowable lengths.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the minimum and maximum allowable lengths in your comments as well.
Answer:
#Take input from user
password = input("Enter the password: ")
#Find the length of the password
length_password = len(password)
#Initialize the max and min length of password
max_length = 10
min_length = 8
#Check if the length of password is within the min and max values
if len(password) >= min_length and len(password) <= max_length:
#Check if the sub-string "umgc" is present in the password
if password.lower().find("umgc") == -1:
#Check if the password have "#" in it and not at position first and last
if "#" in password and password[0] != '#' and password[-1]!='#':
#If all conditions true print the success statement.
print("You have entered a valid password!")
else:
#Error if # is not used or used at illegal places
print("Invalid password!")
else:
#Error if the password has the string "umgc"
print("Invalid password!")
else:
#Error if the length of string is not within specified ranges.
print("Invalid password!")
