Overview

The theme provides Python code demonstration functionality, supporting online execution of Python code.

Installation

Online Python execution is powered by pyodide. Please ensure pyodide is available before use.

::: npm-to

npm install pyodide

:::

Configuration

This feature is disabled by default. You can enable it through configuration.

export default defineUserConfig({
  theme: plumeTheme({
    markdown: {
      repl: {
        python: true,
      },
    },
  })
})

Usage

Use the ::: python-repl container syntax to wrap Python code blocks. The theme will detect the code blocks and add execution buttons.

::: warning The support for python-repl is limited and currently only supports:

• Execution of basic Python syntax (no backend dependencies)
• Import of basic Python libraries
• Standard output stream (stdout) capture
• If the last statement is an expression (and the code doesn't end with a semicolon), the expression value will be returned
• Exception message output

:::

Read-only Code Demo

Python code demos are read-only by default and cannot be edited.

::: python-repl title="Custom Title"
```python
# your python code
```
:::

Editable Code Demo

For online editing and execution, wrap the code block in the ::: python-repl editable container syntax.

::: python-repl editable title="Custom Title"
```python
# your python code
```
:::

Examples

Print Content

Input:

::: python-repl
```python
def hello_world():
    return 'Hello World!'

hello_world()
```
:::

Output:

::: python-repl

def hello_world():
    print('Hello World!')

hello_world()

:::

Arithmetic Operations

::: python-repl

def mul(a: int, b: int) -> int:
    return a * b

print(mul(-2, 4))

:::

Editable Code Demo

Input:

::: python-repl editable
```python
class Contact:
    def __init__(self, id: int, email: str):
        self.id = id
        self.email = email

contact = Contact(1, 'mary@gmail.com')
print(contact.id)
```
:::

Output:

::: python-repl editable

class Contact:
    def __init__(self, id: int, email: str):
        self.id = id
        self.email = email

contact = Contact(1, 'mary@gmail.com')
print(contact.id)
