This lesson provides an overview of the powerful and flexible Python string formatting methods. Both literal and variable strings may be formatted.
- [Narrator] Python has rich string formatting capabilities.…Here in Komodo, I've opened a working copy…of Hello.py from chapter 11 of the exercise files.…Python 3 uses a string method, called format,…to format strings, and it works like this.…If I create a variable, X equals 42,…and here in the string I can say,…"The number is,"…and I use these curly braces for a placeholder,…and I type format,…and give format the variable X,…and when I run it, you'll notice it says,…"The number is 42."…So, in some languages, they call this string interpolation,…but here, the method of the madness…is exposed by allowing us to use…the format method, like that.…
The curly brackets are a placeholder,…and the format method specifies values for the placeholder.…If you have multiple values,…say Y is 73, and I want to…give another number here,…I can specify the second value in format with a comma,…and when I run it, you see it displays both numbers.…You can name your variables, like this,…xx, and bb,…and then in the format,…you can say xx equals, and bb equals.…
