Create Markdown documents from within your Python code.

Markdown Writer

Create Markdown documents from within your Python code.

I recently worked on a data science project in which I had to generate a Markdown report to display interim results from within my Python script. I was unsatisfied by how clunky is felt, particulary to write things like lists. For example, if you want to output a list of bullets from a list, you would have to do something like this:

output = ''
for item in my_list:
    output += f"- {item}\n"

# OR
output = "\n".join([f"- {item}" for item in my_list])

It gets more complicated (and ugly) very quickly when writing nested lists, and even keeping track of the required number of newline characters takes more effort than it should for such a simple task.

The purpose of this library is to create simple abstractions to make this simple task effortless. To turn your Python list into a Markdown list, simply call md.list(my_list).

# Instantiate MarkdownWriter() at the top of your script
md = MarkdownWriter()
# And then build your output step-by-step
md.list(my_list)

See ./examples/example.py for more examples.

Example usage

Code Block Example

md.code_block('Hello, World!')

Tables from Pandas

df = pd.DataFrame({
    "Name": ["Alice", "Bob", "Charlie"],
    "Age": [25, 30, 35],
    "City": ["Cape Town", "Johannesburg", "Durban"]
})
md.table_from_pandas(df)

Name	Age	City
Alice	25	Cape Town
Bob	30	Johannesburg
Charlie	35	Durban

List Example

# This is how you create a list:
sports = ["Rugby", "Football", "Cricket"]
md.list(sports)

• Rugby
• Football
• Cricket

Nested List Example

Using list levels

A simple way to create nested lists is by specifying the list level.

# This is how you create a nested list:
md.list(["Sports"], level=1)
md.list(["Rugby", "Football", "Cricket"], level=2)

• Sports

  • Rugby
  • Football
  • Cricket

Using a dictionary

You can also create nested lists from a dictionary.

# This is how you create a nested list from a dictionary:
produce = {
    "Fruits": {
        "Citrus": ["Orange", "Lemon", "Lime"],
        "Berries": ["Strawberry", "Blueberry", "Raspberry"]
    },
    "Vegetables": {
        "Leafy": ["Spinach", "Lettuce"],
        "Root": ["Carrot", "Beetroot"]
    }
}
md.nested_list_from_dict(produce)

• Fruits
  • Citrus
    • Orange
    • Lemon
    • Lime
  • Berries
    • Strawberry
    • Blueberry
    • Raspberry
• Vegetables
  • Leafy
    • Spinach
    • Lettuce
  • Root
    • Carrot
    • Beetroot

Numbered List Example

# This is how you create a numbered list:
sports = ["Rugby", "Football", "Cricket"]
md.numbered_list(sports)

1. Rugby
2. Football
3. Cricket

Image Example

Cape Town is a spectacular city.

md.image(alt_text='Cape Town', url=url)
