In Python 3, print() is now a function, not a statement. This is a major change from earlier versions, and is different from many other languages. print() is also used for formatting strings and data.
- [Instructor] The Python print function is simple…and powerful and it's probably a bit different…than what you're used to in other languages.…Here in Komodo I've opened a working copy of hello.py…from chapter two of the exercise files.…And you'll notice that down here on line four,…I have a print function with a literal string…which says hello world.…And so if I save and run this,…you see the output says hello world.…Now if I want to print a variable value in the string,…I'll use the format method.…
Which is actually a method of the string object.…And so I put a placeholder in here…with a pair of curly braces.…And I say dot format.…And I'll put a value up here, I'll make a variable.…X equals 42.…And I put that x in the format method.…And when I save and run,…you see now we get a 42 down there in our output.…The format method is very powerful,…and very flexible and we'll cover it…in detail later in the course.…But for now you know enough to use it in many many cases.…
It's worth noting that this is not a function or a method…
