What are some examples of f-strings in Python 3?

F-strings, or formatted string literals, allow you to embed expressions inside string literals. For example:

name = 'Alice'
age = 30
print(f'{name} is {age} years old.')  # Output: Alice is 30 years old.

Can you show me more complex examples?

Sure! Here's a more complex example:

import math
radius = 5
area = math.pi * (radius ** 2)
print(f'The area of a circle with radius {radius} is {area:.2f}.')  # Output: The area of a circle with radius 5 is 78.54.

How do f-strings handle different data types?

F-strings can handle various data types seamlessly. For instance:

value = 123.456
print(f'The value is {value:.1f}.')  # Output: The value is 123.5.

Are there any limitations to using f-strings?

Yes, f-strings require Python 3.6 or later, and you can't use them in f-string expressions if they contain certain characters like !.
