Project Overview

This Python Password Generator helps create strong, random passwords using a combination of lowercase, uppercase, digits, and special characters. It’s a beginner-friendly project that demonstrates Python concepts like random number generation, loops, input validation, and list manipulation.

Users can customize the password length, and the generator ensures at least one character from each type is included, making it suitable for real-world password needs.

Creating strong passwords is essential for protecting user accounts, applications, and sensitive data. This Python console-based password generator helps you create secure, random passwords using a combination of letters, numbers, and special characters. It is ideal for beginners learning Python as well as developers who want a simple password generation utility.


What You Will Learn

  • How to generate random characters using Python's random and string modules
  • How to ensure password security by including all character types
  • Basic input validation and error handling in Python
  • How to shuffle lists to avoid predictable patterns
  • Beginner-friendly project logic for console applications

The following code script will generate strong and secure passwords. It will have Features like:

  • 👉 Prompts for custom password length (minimum 8)
  • 🔡 Includes lowercase, uppercase, digits, and symbols
  • ✅ Ensures at least one of each character type
  • 🔀 Shuffles characters for randomness

⚙️ How This Password Generator Works

The program first asks the user to enter a desired password length (minimum 8 characters). It then guarantees that the password contains:

  • At least one lowercase letter
  • At least one uppercase letter
  • At least one digit
  • At least one special character

After ensuring all required character types are included, the remaining characters are selected randomly and shuffled to prevent predictable patterns. 


import random
import string

print("🔐 Welcome to the Password Generator!")

# Ask for password length
while True:
    try:
        length = int(input("👉 Enter desired password length (8 or more): "))
        if length < 8:
            print("⚠️ Password should be at least 8 characters long.")
        else:
            break
    except ValueError:
        print("❌ Please enter a valid number.")

# Define character sets
letters = string.ascii_letters
digits = string.digits
symbols = "!@#$%^&*()_+-=[]{}|;:,.<>?/"

# Combine all characters
all_chars = letters + digits + symbols

# Ensure password contains at least one of each type
password = [
    random.choice(string.ascii_lowercase),
    random.choice(string.ascii_uppercase),
    random.choice(digits),
    random.choice(symbols)
]

# Fill the rest randomly
while len(password) < length:
    password.append(random.choice(all_chars))

# Shuffle to avoid predictable pattern
random.shuffle(password)

# Convert list to string
final_password = ''.join(password)
print(f"✅ Your generated password is: {final_password}")


📌 Sample Output

🔐 Welcome to the Password Generator!
👉 Enter desired password length (8 or more): 12
✅ Your generated password is: A9@kP!2rQ$eL

Each time you run the program, a completely different password is generated, ensuring high randomness and security.

💡 When to Use This Password Generator

  • Creating secure passwords for testing applications
  • Learning Python randomization techniques
