String interpolation refers to embedding variable content inside a string literal. While not traditionally associated with Python, recent updates have made incorporating dynamic values into static strings more accessible.

Let’s explore two primary approaches — f-strings and template strings — to enhance our Python repertoire while promoting cleaner and more maintainable code.

F-Strings

Available since Python 3.6, f-strings enable developers to seamlessly merge expression results into string literals via embedded curly braces {}. This approach fosters improved legibility and efficiency, reducing boilerplate common in previous solutions.

Basic Example:

first_name = "Jane"
last_name = "Doe"

# Using traditional string formatting
print("Full Name: " + first_name + " " + last_name)  # Full Name: Jane Doe

# With f-strings
print(f"Full Name: {first_name} {last_name}")  # Full Name: Jane Doe
