Casting input to get what you want:
If you want numeric data from a string, you must assume that the user gave you what you want:
age=input(“What is your age?”)
print(“In 5 years you will be %i years old.” % int(age)+5 )
If you want (bad idea) you could cast the whole input line:
age=int(input(“What is your age?”))
print(“In 5 years you will be %i years old.” % age+5 )
You could also to the cast in its own line:
age=input(“What is your age?”)
age=int(age)
print(“In 5 years you will be %i years old.” % age+5 )
What if users don’t do what I want them to do?
What if they enter a float when I want an int?
What if they enter text or a combination of text and numbers when I just want numbers?
It can get tricky to deal with. We’re not going to worry about that in this introduction.
