Comparison of string formatting | %operator vs str.format vs f- string | Coding through visuals
In this video, we'll explore the three major methods of string formatting in Python:
1. The % operator: This is the oldest method, resembling printf-style formatting. It's simple but lacks flexibility and alignment options.
2. The str.format method: More modern than %, it uses curly braces for placeholders and offers more control over formatting. However, it can be verbose for complex expressions.
3. f-string literals: Introduced in Python 3.6, these are concise and elegant, allowing expressions directly in strings. They're powerful but not backward-compatible and can be risky with untrusted input.
We'll cover the advantages, disadvantages, and suitability of each method, with examples and benchmarks for performance and readability. By the end, you'll have a comprehensive understanding of Python string formatting, enabling you to write efficient and clear code.
