Jason, Mark and Dave have addressed this part of your question already.

What do you mean here? You're thinking that you have to convert them to strings
before passing them to the print function? Actually, the string formatting
operator, the percent sign, combined with the 's' will convert for you, using
the str() method. So, the code above is redundant. Just use:
print('This arg is %s %s' % k, v)
Take care,
