What are the differences between string formatting and concatenation in Python 3.12?

What are the differences between string formatting and concatenation in Python 3.12?

In Python 3.12, string formatting allows you to embed variables directly into strings using f-strings or the format method, while concatenation simply joins strings together using the '+' operator.

Can you give me an example of both methods?

Sure! For concatenation: name = 'Alice'; greeting = 'Hello, ' + name results in 'Hello, Alice'. For formatting: greeting = f'Hello, {name}' also results in 'Hello, Alice'.

Which method is preferred for readability?

String formatting, especially with f-strings, is generally preferred for readability as it clearly shows the variables being used within the string.

Are there any performance differences between the two?

Yes, string formatting can be slightly slower than concatenation for a small number of strings, but for larger strings or multiple variables, formatting is often more efficient.
