Python

Regular Python

Python code is executed in the current process, with isolated global variables.

To capture the output of your code, Markdown Exec patches the print function so that it writes to a buffer instead of standard output.

```python exec="1"
print("**Hello world!**")
```

See the Gallery for more complex examples.

Python console code

Code blocks syntax-highlighted with the pycon identifier are also supported. These code blocks will be pre-processed to keep only the lines starting with >>> , and the chevrons (prompt) will be removed from these lines, so we can execute them.

```pycon exec="1" source="console"
--8<-- "usage/source.pycon"
```

It also means that multiple blocks of instructions will be concatenated, as well as their output:

```pycon exec="1" source="console"
--8<-- "usage/multiple.pycon"
```
