How to Use a List to Format a String in Python

The format() method allows you to create a formatted string by using data stored in a list.

Example

Let’s start by creating a list with three elements:

lista = ['Italy', 'Rome', 'Europe']

Next, we'll create a string that includes placeholders referencing the list using the format() function.

stringa = "The capital of {0[0]} is {0[1]}. It’s located in {0[2]}.".format(lista)

The format() function accesses the list and replaces the placeholders with the corresponding values from the list.

• {0[0]} = Italy
• {0[1]} = Rome
• {0[2]} = Europe

Finally, we'll print the formatted string using the print() function:

print(stringa)

The output will be:

The capital of Italy is Rome. It’s located in Europe.

And there you have it!
