You write Python f-strings by writing two parts: f (or F) and a string (either single, double, or triple quotes). The '%' operator is primarily limited by the fact that it is a binary operator, and therefore can take at most two arguments. Using a dictionary (Python 2.x) >>> data = {'first': 'Hodor', 'last': 'Hodor!'} >>> ' {first} {last}'.format (**data) 'Hodor Hodor!' Using a dictionary (Python 3.2+) The input function displays a string of text, and it awaits an input from the user.

Since the name variable contains the word Steve, then Python looks at the string Hello {0}, it sees there is a magical item called a placeholder there, and it understands that it needs to look further ahead for a.format command.

Hi, thanks for the answer but I've tried passing it the list and I get the following: Right, sorry. . Find out what the Python "pass" statement is meant for.

Placeholder is defined by using curly brackets: {}. Use print ("%s" + ", %s" * (len(input) - 1) + ".") The smart money, on any code of complexity, is to use placeholders. Here, you can see that %s will hold a place(value) from %tutorial and the value of tutorial is TutorialBrain. With this site we try to show you the most common use-cases covered by the old and new style string formatting API with practical examples..
