Your First Python Program

Let's write your first line of Python code!

The print() Function

In Python, we use

print()

to display text on the screen.

print("Hello, World!")

How It Works:

```
print
```
is a function - it performs an action
The parentheses
```
()
```
contain what we want to print
The quotes
```
""
```
tell Python this is text (called a string)
