The purpose of the 'f-string' in Python is to provide a concise and convenient way to embed expressions inside string literals. Introduced in Python 3.6, f-strings allow you to include variables and expressions within curly braces {} that are evaluated at runtime and formatted into the resulting string. This makes string formatting easier to read and write compared to older methods.
Here’s a simple example:
name = "Alice"
print(f"Hello, {name}!")This will output: Hello, Alice!
F-strings also support format specifiers, allowing for more control over how values are presented:
x = 3.14159
print(f"The value of pi is approximately {x:.2f}.")This will output: The value of pi is approximately 3.14.
