Or do you mean something like 5%2, which means the remainder upon dividing 5 by 2?

The most up-voted answer to https://stackoverflow.com/questions/9... explains two of the uses of % in Python, and another answer also discusses Jupyter/IPython magic commands.

Hilarious, I have no idea why the first one that occurred to me was formatting.

Without further information, perhaps we should close the question: too imprecise.

I presume you are talking about string formatting. In this case, most Python tutorials will tell you how to format/replace strings inside of other strings with various variables. An example from one tutorial:

>>> name = 'Bob'
>>> 'Hello, %s' % name
"Hello, Bob"

Here is an example using interact to show computations nicely, which is a primary way to use string formatting in Sage usefully.

However, one should point out that the new-style formatting ('Hello, {}'.format(name) in the linked tutorial) is probably mostly recommended.

or simply f'Hello {name}'
