Question

How do I insert multiple variables with string formatting?

Answer

So long as your number of %s placeholders matches the number of variables you are providing after the %, it will insert them in the order in which you provide them. Take a look over the code below for a better understanding:

var1 = “awesome”
var2 = “ever”
print “Codecademy has the most %s coding lessons %s!” % (var1, var2)
# displays: “Codecademy has the most awesome coding lessons ever!”

If you don’t have the same number of placeholders as variables provided to it, you will get an error message like these:
TypeError: not all arguments converted during string formatting
TypeError: not enough arguments for format string
The first means you have more variables than placeholders, and the second means you have more placeholders than variables provided. This is a very common issue, so be on the lookout!
