What are the differences between lexify and asciify in Faker

Lexify

- Functionality: The `lexify` method replaces placeholders in a given string with random letters. The placeholders are represented by question marks (`?`).

- Example: If you call `lexify('Hello ???')`, it might return something like `Hello abc`, where `abc` is a random combination of letters.

- Usage: This method is useful when you need to generate strings that resemble words or identifiers, maintaining the alphabetic structure.

Asciify

- Functionality: The `asciify` method replaces placeholders in a string with random ASCII characters. The placeholders are represented by asterisks (`*`).

- Example: If you call `asciify('Hello ***')`, it might return something like `Hello R6+`, where `R6+` is a random combination of ASCII characters, including letters, numbers, and symbols.

- Usage: This method is ideal when you need to create strings that may include a wider range of characters, including non-alphabetic ones.

Summary of Differences

- Placeholder Characters:
- `lexify` uses `?` for letters.
- `asciify` uses `*` for ASCII characters.

- Character Set:
- `lexify` generates only letters (A-Z, a-z).
- `asciify` generates a mix of letters, numbers, and symbols.

These methods allow for versatile string generation depending on the requirements of your application, whether you need purely alphabetic strings or a broader ASCII range.
