Nested f-strings in python

Nested f-strings in python

In Python 3.8 and later versions, you can use nested f-strings to embed one f-string inside another. This allows you to format strings in a more concise and readable way. Here's an example of how you can use nested f-strings:

name = "Alice" age = 30 city = "Wonderland" # Nested f-string message = f"My name is {name}, and I am {age} years old. I live in {city.upper()}." print(message)

In this example, the nested f-string {city.upper()} is used inside the outer f-string. The result is a formatted string that includes the value of name, age, and an uppercase version of city.

You can use any valid Python expression within the curly braces of a nested f-string. This makes it convenient for performing various operations while constructing your formatted string.

Keep in mind that f-strings are available in Python 3.6 and later versions, but nested f-strings were introduced in Python 3.8. If you're using an older version of Python, you won't be able to use nested f-strings directly.
