how to take a symbol as a string

Question

This question is quite simple but I cannot find the good way to do that....

The thing is that I am trying to print on screen the progress of an operation...just for test purposes, but I am having an error when I try to print something like that: "Completed 30%"

The problem is that "%" is being taken as an argument here:

Here is the piece of the code

print "Completed: %s % " % (100*loops/totalLoops)

And here is the error:

print "Completed: %s %" % (100*loops/totalLoops)
ValueError: incomplete format

There should be an easy fix for that stupid thing...but I cannot find it.

@eumiro We should add one then, that post clearly shows up more in [Google search](https://www.google.co.in/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=escape+%25+in+python+string)(44K views). — Ashwini Chaudhary, Jan 30 '15 at 13:35

Use %% to print a single %:

print "Completed: %s %%" % (100*loops/totalLoops)

or use the new format:

print "Completed: {0} %".format(100. * loops / totalLoops)

which even allows you to print float as percents (without multiplying them with 100):

print "Completed: {0:.0%}".format(1. * loops / totalLoops)

For

loops = 2
totalLoops = 7

prints

'Completed: 29%'
