Formatting string to keep trailing zeros to runtime-set precision

In Python (3), I would like to write a number to a string and keep trailing zeros to a specified precision. The trick is (and why this question is different from others I've seen on this site), the precision is to be specified at run-time based on other factors, and the precision will not necessarily be the same across all the numbers I am writing to a string.

Something like

'{0:.5f}'.format(number)

But with the 5 being a variable.

How would I go about doing this?

You can provide the precision as a variable too `'{0:.{prec}}f'.format(number, prec=5)` – rrawat Jun 01 '19 at 18:46
