Python’s f-strings (formatted string literals) are one of the best features introduced in Python 3.6. They make string formatting faster, cleaner, and more readable than older methods like .format() and % formatting.

But did you know? f-strings can do much more than simple variable interpolation?

In this article, we’ll explore 5 powerful f-string tricks that every Python developer should know! Let’s dive in.

1. Inline Expressions in F-Strings

F-strings allow you to evaluate expressions directly inside the curly braces {}. No need for extra variables or function calls before formatting.

Example:

name = "John"
age = 25

# Old way
print("{} will be {} next year.".format(name, age + 1))

# F-string way
print(f"{name} will be {age + 1} next year.")

Output:

John will be 26 next year.
