Inputting Whole Numbers
Keyboard input arrives as text. To use it as a whole number, wrap input() with int():
age = int(input("How old are you? "))
print("Have you really lived for", age, "years?")Example run:
How old are you? 99
Have you really lived for 99 years?
Inputting Numbers Task 1 – Zoo Visits
Ask how many times the user has been to the zoo, convert the answer to an integer, then print a sentence using the number.
zoo_visits = int(input("How many times have you been to the zoo? "))
print("You've been to the zoo", zoo_visits, "times? I love animals!")Inputting Decimal Numbers
For values with a decimal point, use float() instead:
miles = float(input("How far have you walked today? "))
print("You really walked", miles, "miles? Wow!")If the user enters 5.6, the printout confirms the distance.
Inputting Numbers Task 2 – Height
Ask for height in metres as a float, then print it in a sentence.
