python - How do I print a '%' sign using string formatting?

Question

I've made a little script to calculator percent; however, I wish to actually include the % within the message printed...

Tried this at the start - didn't work...

oFile.write("Percentage: %s%"
" % percent)

I then tried "Percentage: %s"%" " % percent" which didn't work.

I'd like the output to be:

Percentage: x%

I keep getting

TypeError: not all arguments converted during string formatting

To print the % sign you need to 'escape' it with another % sign:

percent = 12
print "Percentage: %s %%
" % percent  # Note the double % sign
>>> Percentage: 12 %
