Target headers

Syntax

Example

Note

(target_header)=
(myst_cheatsheet)=
# MyST Cheat Sheet

See below how to reference target headers.

Referencing target headers

Targets can be referenced with the ref inline role which uses the section title by default:

{ref}`myst_cheatsheet`

You can specify the text of the target:

{ref}`MyST syntax lecture <myst_cheatsheet>`

Another alternative is to use Markdown syntax:

[MyST syntax lecture](myst_cheatsheet)

Quote

Example

Note

> text
> this is a quote

Thematic break

Syntax

Example

Note

---
This is the end of some text.

Example:

```{code-cell} ipython3
from myst_nb import glue
my_variable = "here is some text!"
glue("glued_text", my_variable)
```

Here is an example of how to glue text: {glue:}`glued_text`

Result:

from myst_nb import glue
my_variable = "here is some text!"
glue("glued_text", my_variable)
'here is some text!'

Here is an example of how to glue text: 'here is some text!'

See Gluing variables in your notebook for more information.

Example:

```{code-cell} ipython3
from myst_nb import glue
import numpy as np
import pandas as pd

ss = pd.Series(np.random.randn(4))
ns = pd.Series(np.random.randn(100))

glue("ss_mean", ss.mean())
glue("ns_mean", ns.mean(), display=False)
```

Here is an example of how to glue numbers: {glue:}`ss_mean` and {glue:}`ns_mean`.

Result:

from myst_nb import glue
import numpy as np
import pandas as pd

ss = pd.Series(np.random.randn(4))
ns = pd.Series(np.random.randn(100))

glue("ss_mean", ss.mean())
glue("ns_mean", ns.mean(), display=False)
-0.3449539181631335

Here is an example of how to glue numbers: -0.3449539181631335 and -0.04776110981685107.

See Gluing variables in your notebook for more information.

Example:

```{code-cell} ipython3
from myst_nb import glue
import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 200)
y = np.sin(x)
fig, ax = plt.subplots()
ax.plot(x, y, 'b-', linewidth=2)

glue("glued_fig", fig, display=False)
```

This is an inline glue example of a figure: {glue:}`glued_fig`.
This is an example of pasting a glued output as a block:
```{glue:} glued_fig
```

x = np.linspace(0, 10, 200)
y = np.sin(x)
fig, ax = plt.subplots()
ax.plot(x, y, 'b-', linewidth=2)

glue("glued_fig", fig, display=False)
../_images/cheatsheet_7_1.png

This is an inline glue example of a figure: ../_images/cheatsheet_7_0.png. This is an example of pasting a glued output as a block:

../_images/cheatsheet_7_0.png

Example:

```{code-cell} ipython3
import sympy as sym
x, y = sym.symbols('x y')
z = sym.Function('z')
z = sym.sqrt(x**2+y**2)
glue("example_eq", z, display=False)
```

To glue a math equation try
```{glue:math} example_eq
:label: glue-eq-example
```

Result:

import sympy as sym
x, y = sym.symbols('x y')
z = sym.Function('z')
z = sym.sqrt(x**2+y**2)
