Print Variable In Jupyter Notebook Markdown Cell Python

@nilansh bansal’s answer works great for Jupyter Notebooks. Unfortunately, it doesn’t work for JupyterLab because the plugin is no longer supported (as is the case for all nbextension plugins). Since JupyterLab gains popularity, I wanted to complement the answers so far because it took me quite some time to find a solution. This is because until now there is no plugin compatible with JupyterLab. I have found the following solution for myself by combining this and this SO answers:

from IPython.display import Markdown as md
# Instead of setting the cell to Markdown, create Markdown from withnin a code cell!
# We can just use python variable replacement syntax to make the text dynamic
n = 10
md("The data consists of {} observations. Bla, Bla, ....".format(n))

Alternatively, the last line can be simplified as suggested by @Igor Fobia for Python >3.6:

md(f"The data consists of {n} observations. Bla, Bla, ....")

This leads to the desired output. However, it has the huge disadvantage that the code cell will still be visible when exporting the NB. This can be solved though:

1. Add a tag to the code cell, i.e. name it “hide”
2. Configure nbconvert to ignore the tagged cells, e.g. by adding this c.TagRemovePreprocessor.remove_input_tags = {"hide"} to your ~/.jupyter/jupyter_notebook_config.py config file

I have written a detailed blog-post about how I implemented this solution for publishing Notebooks on my blog. If you use JupyterLab < 2.0, you could install the jupyterlab-celltags plugin for JupyterLab to simplify the cell tagging.
