Unlike in earlier versions of Python, strings are now first-class objects in Python 3. This lesson shows you how to use object methods on both literal and variable strings.
- Strings are first class objects in Python Three.…This is different than many other languages, and it's even…a little bit different than Python Two, even though strings…were objects in Python Two, they weren't fully first class…objects, and the string interface is far more consistent now…But change is still change, so if you're familiar with…Python Two strings, you'll want to pay close attention here.…Here in Komodo, I have opened a working copy of hello.py…from chapter 11 of the exercise files, and let's start…taking a look at a string as an object.…
Here we have a literal string, and even though it's a…literal string, I can still call methods on it.…So I can call the upper method and when I run this,…we get "hello world" in all capital letters.…Or I can run the swap case…method, and it'll simply swap the case.…If it was capital in the original string, it'll make it…lowercase in the output string.…In fact, it's so common to call methods on a literal string…in Python Three, string formatting is commonly…done like this.…
