Python Cyber Security - Check password strength
Python Cyber Security: Exercise-3 with Solution
Write a Python program to check if a password meets the following criteria:
At least 8 characters long and
Contains at least one uppercase letter, one lowercase letter, one digit, and one special character (!, @, #, $, %, or &)
If the password meets the criteria, print a message that says "Valid Password." If it doesn't meet the criteria, print a message that says "Password does not meet requirements."
Sample Solution:
Python Code:
# Solution to Exercise 3
import re
def validate_password(password):
# Check if the password has at least 8 characters
if len(password) < 8:
return False
# Check if the password contains at least one uppercase letter
if not re.search(r'[A-Z]', password):
return False
# Check if the password contains at least one lowercase letter
if not re.search(r'[a-z]', password):
return False
# Check if the password contains at least one digit
if not re.search(r'\d', password):
return False
# Check if the password contains at least one special character
if not re.search(r'[[email protected]#$%^&*(),.?":{}|<>]', password):
return False
# If all the conditions are met, the password is valid
return True
password = input("Input your password: ")
is_valid = validate_password(password)
if is_valid:
print("Valid Password.")
else:
print("Password does not meet requirements.")
Sample Output:
Input your password: Aji1#der Valid Password. Input your password: A123d$%h Valid Password. Input your password: A12&ki1 Password does not meet requirements. Input your password: KI342$&H Password does not meet requirements.

Python: Tips of the Day
Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value:
Example:
def tips_map_values(obj, fn): ret = {} for key in obj.keys(): ret[key] = fn(obj[key]) return ret users = { 'Owen': { 'user': 'Owen', 'age': 29 }, 'Eddie': { 'user': 'Eddie', 'age': 15 } } print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}
Output:
{'Owen': 29, 'Eddie': 15}
