Code Explanation

Libraries Used

• random: To randomly shuffle and sample characters for the password.

Main Functions

ask_user()

This function prompts the user to choose whether to include numerals, capital letters, small letters, and symbols in their password. Based on the user's input, it constructs a string of allowed characters.

Password Length

The user specifies the password length. If the input is invalid (not a number), an error message is displayed, and the input is re-requested.

Password Generation

Using the random.sample() method, the script generates a random password by selecting characters from the user-defined pool of allowed characters.

Error Handling

• If no character types are selected, the script prompts the user again.
• If the desired password length exceeds the number of available characters, an error message is displayed.

Customization

• To add or modify the character pool (e.g., include additional symbols), edit the variables in the script:

  numbers = '1234567890'
  capital_letters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
  small_letters = 'abcdefghijklmnopqrstuvwxyz'
  symbols = '@#_&-+()/*:;!?.~`\''"|=\u00b0<>{}\%[]'
