2 ways to format a string in Python


Formatted string literals, commonly known as f-strings, are strings prefixed with 'f' or 'F'. These strings can contain replacement fields, enclosed in curly braces ({}).

name = 'John'
age = 32

print(f'{name} is {age} years old') # 'John is 32 years old'


The str.format() method works very much alike f-strings, the main difference being that replacement fields are supplied as arguments instead of as part of the string.

name = 'John'
age = 32

print('{0} is {1} years old'.format(name, age)) # 'John is 32 years old'
