How do I add the format for underlining text in xlsxwriter?

Just want to know how to create a variable for underlining text in the package xlsxwriter. For example, this is the one I created for making it bold:

bold_format = workbook.add_format({'bold': True})

Sorry if the answer is blatantly obvious, I tried looking it up to no avail.
