What are some advanced features of f-strings in Python 3.10?

In Python 3.10, f-strings support the new syntax for the match statement, allowing for more complex expressions.

Can you give me an example of using f-strings with the match statement?

Sure! You can use f-strings to format the output of a match statement like this:

value = 10
result = f'The value is {match value:
    case 10: "Ten"
    case _: "Not Ten"}'

This will output: 'The value is Ten'.

What about using f-strings with dictionaries?

You can easily access dictionary values within f-strings. For example:

d = {'name': 'Alice', 'age': 30}
print(f'{d['name']} is {d['age']} years old.')

This will output: 'Alice is 30 years old.'.

Are there any performance improvements with f-strings in Python 3.10?

Yes, f-strings are generally faster than other string formatting methods, and Python 3.10 has optimized their performance further.
