# md

Write markdown.

This function takes a string of markdown as input and returns an `Html` object. Output the object as the last expression of a cell to render the markdown in your app.

## Usage

```python theme={null}
mo.md("# Hello, World!")
```

```python theme={null}
mo.md(
    r'''
    The exponential function $f(x) = e^x$ can be represented as

    \[
        f(x) = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \ldots.
    \]
    '''
)
```

## Signature

```python theme={null}
mo.md(text: str) -> Html
```

## Parameters

<ParamField path="text" type="str" required>
  A string of markdown.
</ParamField>

## Returns

<ParamField path="Html">
  An `Html` object.
</ParamField>

## Interpolation

You can interpolate Python values into your markdown strings, for example using f-strings. `Html` objects and UI elements can be directly interpolated.

```python theme={null}
text_input = mo.ui.text()
mo.md(f"Enter some text: {text_input}")
```

For other objects, like plots, use marimo's `as_html` method to embed them in markdown:

```python theme={null}
import matplotlib.pyplot as plt

plt.plot([1, 2])
axis = plt.gca()
mo.md(f"Here's a plot: {mo.as_html(axis)}")
```

## LaTeX

Enclose LaTeX in single `$` signs for inline math, and double `$$` for display math or square brackets for display math. (Use raw strings, prefixed with an "r", to use single backslashes.)

```python theme={null}
mo.md(
    r'''
    The exponential function $f(x) = e^x$ can be represented as

    \[
        f(x) = 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \ldots.
    \]
    '''
)
```
