Press the key above the tab button 3 time to produce this character(s), ```.
This character is called Grave Accent.
Then write language code (cpp, c, python, rb, java, bash etc.)
Write your code.
Then type three grave accents ```again like this,
```python
print("something")
```
and the result will be like this,
print("something")
Try to edit your code(s) with this now. Formatted codes are easier to be read then unformatted ones. They also looks cool.
