Your first program
Python programs are just text files that the Python interpreter reads top to bottom. The most useful thing to learn first is how to show output:
print("Hello, World!")
printis a function: a reusable piece of code you can call by name.- The text in quotes is a string, a sequence of characters.
- Everything after a
#on a line is a comment – Python ignores it, humans read it.
You can call print as many times as you like; each call writes on a new line.
Try it
Change the program on the right so it prints these two lines, then press Run:
Hello, Python!
I am learning to code.
When the output matches, the lesson is marked complete automatically.
