Issue: Markdown Formatting Not Working in Jupyter Notebook

[laguill]

Hello,

I am using a Quarto notebook and a custom Python script with a function that returns a formatted string.
The function is supposed to return a string formatted in Markdown, but when I display it in the notebook, the Markdown formatting (e.g., bold text) is not applied.

Custom Python Script (tools.py)

def myfunc(title, df):
    info = f"""
    Title: **{title}**
    Shape: **{df.shape}**
    """
    return info

Quarto notebook

```{python}
from tools import myfunc
from IPython.display import Markdown, display
import pandas as pd

# Example DataFrame
dataframe = pd.DataFrame({'col1': range(12), 'col2': range(12)})

# Display the Markdown
display(Markdown(myfunc("title", dataframe)))
```

Expected Output

Title: title
Shape: (12, 2)

Actual Output
"Title: **title** Shape: **(12, 2)**"
The Markdown formatting (bold text) is not applied, and the string is displayed as plain text.

Question

Is there a misconfiguration in my Quarto notebook or in the way I am using the Markdown function from IPython.display?
How can I ensure that the returned string is correctly formatted in Markdown?

Thanks for your help

FYI, your issue is unrelated to Quarto, it's a pure Python issue and understand of """ block.

Look at what you are emitting with your function using keep-md: true.

You are not outputting:

Title: **title**
Shape: **(12, 2)**

But

    Title: **title**
    Shape: **(12, 2)**

Which is not at all the same thing.

You need to refactor your code to produce unindented output, for example:

import textwrap

def myfunc(title, df):
    info = textwrap.dedent(f"""
    Title: **{title}**
    Shape: **{df.shape}**
    """)
    return info

I found a solution by adding <br /> as cariage return

def myfunc(title, df):
    info = f"""Title: **{title}** <br />
    Shape: **{df.shape}**<br />
    """
    return info

Your solution is HTML specific as <br> is not Markdown (even if Pandoc can automatically detect some things, relying on that is really not the safest/robust approach for your code).

There are two ways in Markdown (Pandoc) to break a line in the same paragraph:

• 2 or more trailing spaces
• trailing \
