Generate Random Passwords

Certification: Intermediate Level Accuracy: 37.93% Submissions: 29 Points: 15

Write a Python function to generate a random password of a specified length. The password should include a mix of uppercase letters, lowercase letters, digits, and special characters.

Example 1
    
  
  • Input: length = 8
    • 
  
  • Output: "A1b@C2d#" (Note: actual output will vary due to randomness)
    • 
  
  • Explanation: 
      
    
    • Step 1: Define character sets for uppercase letters, lowercase letters, digits, and special characters.
      • 
    
    • Step 2: Ensure the password includes at least one character from each set.
      • 
    
    • Step 3: Generate remaining characters randomly from all available character sets.
      • 
    
    • Step 4: Shuffle all characters to ensure randomness in the final password.
      • 
    
    • Step 5: Return the generated password of length 8 with characters from all required sets.
      •

Example 2
    
  
  • Input: length = 12
    • 
  
  • Output: "Xy3$Zq9&Wp7*" (Note: actual output will vary due to randomness)
    • 
  
  • Explanation: 
      
    
    • Step 1: Define character sets for uppercase letters, lowercase letters, digits, and special characters.
      • 
    
    • Step 2: Ensure the password includes at least one character from each set.
      • 
    
    • Step 3: Generate remaining characters randomly from all available character sets.
      • 
    
    • Step 4: Shuffle all characters to ensure randomness in the final password.
      • 
    
    • Step 5: Return the generated password of length 12 with characters from all required sets.
      • 
  
    •
Constraints
    
  
  • 4 <= length <= 20
    • 
  
  • Time Complexity: O(n) where n is the length of the password
    • 
  
  • Space Complexity: O(n)

Solution Hints

    
  
  • Use the random module to select characters randomly.
    • 
  
  • Ensure the password contains at least one character from each category (uppercase, lowercase, digit, special character).
    • 
  
  • Combine the selected characters to form the password.
    •

Steps to solve by this approach:

 Step 1: Import necessary modules (random and string)
 
 Step 2: Define character sets for uppercase, lowercase, digits, and special characters
 
 Step 3: Create an empty list to build the password
 
 Step 4: Add at least one character from each character set to ensure complexity
 
 Step 5: Fill the remaining length with random characters from all sets combined
 
 Step 6: Shuffle the password list to randomize character positions
 
 Step 7: Join the list into a string and return the generated password
