Subject: [PATCH] Improve code readability and performance by using f-strings

Using f-strings can improve both the readability and performance.
- F-strings make it easier to embed variables directly in the string, resulting in more concise and easier-to-read code.
- F-strings are often faster than concatenation because they are evaluated at runtime rather than being built up piece by piece.
