Can somebody tell me what I'm doing wrong?


Whenever I finish answering the last question, I'm greeted with this error.


You are doing substitution incorrectly,

# You have to put the type after the %

a = 'string'
print("%s aaaa" % a)

b = 123.1423
print("%.2f bbbb" % b)

It's as easy as that. You have to tell python why type of information you are passing it with substitution.


You just need to put the "%" in front of the "s"
