Posts that include executable code

Executing code with quarto

Quarto makes it easy to include executable code within documents. For example:

Including

```{python}
for i in range(5):
    print(i)
```

Produces:

for i in range(5):
    print(i)

The output of the code is executed and included in the document.

Note

The {} syntax around the python is important for quarto to know to execute the code rather than only display the markdown for it.

Use {{python}} to show {python} in the rendered output without actually executing it as code.

See the Quarto documentation for more examples.

For example, including figures is a really nice feature.

Matplotlib

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)

plt.plot(x, y)
plt.xlabel('x')
plt.ylabel('sin(x)')
plt.title('A simple plot')
plt.show()

Figure 1: A caption can even be included

Plotly

And it work with plotly too!

import plotly.express as px

df = px.data.iris()
fig = px.scatter(df, x="sepal_width", y="sepal_length", 
                 color="species", 
                 marginal_y="violin", marginal_x="box", 
                 trendline="ols", template="simple_white")
fig.show()
