# Syntax Highlighting

Some code:

```Python
def sing_bottles(n:int):
    for i in reversed(range(n)):
        if i > 1:
            print(f"{i} bottles of beer on the wall,")
            print(f"{i} bottles of beer!")
            print("Take one down, pass it around...")
        elif i == 1:
            print("One bottle of beer on the wall,")
            print("One bottle of beer!")
            print("Take it down, pass it around...")
        else:
            print("No more bottles of beer on the wall!")
            print("Go to the store, buy some more...")
            sing_bottles(n)
```

```markdown
This is some *markdown* text with **asterisks**.
```

```
Some basic emojis: 🌎💨🔥
They do render correctly with appropriate box size
(But your mileage may vary, depending on how your
terminal renders emojis and what font you use)
