What are the different string formatting methods in Python?
In Python, there are several string formatting methods: the old %
operator, str.format()
, and f-strings (formatted string literals). Would you like to know more about each one?
Yes, can you explain how f-strings work?
Sure! F-strings, introduced in Python 3.6, allow you to embed expressions inside string literals using curly braces. For example: name = 'Alice'; greeting = f'Hello, {name}!'
.
What about the str.format()
method?
The str.format()
method allows you to format strings by placing placeholders in the string and passing values to the format()
function. For example: '{0} is {1} years old'.format('Alice', 30)
.
Which method is recommended for new Python code?
F-strings are generally recommended for new Python code due to their readability and performance. They are concise and easy to use!
