Python String format()

The format() method formats strings contain "replacement fields" surrounded by curly braces {}.

Anything that is not contained in braces is considered literal text, which is copied unchanged to the output.

Note: If you need to include a brace character in the literal text, it can be escaped by doubling: {{ and }}.

Example

Python Compiler
txt1 = "{0} lucky number is {1}".format("John Doe", 45) txt2 = "{1} lucky number is {0}".format(45, "John Doe") print(txt1) print(txt2)

Output

John Doe lucky number is 45 John Doe lucky number is 45
