Question 3

Which block of code will produce an error? For extra points, which type of error do you think it will produce?

time_until_midnight = "5"
print("There are " + time_until_Midnight + " hours until midnight")

num_hours = "5"
print("There are " + num_hours + " hours until midnight")

time_until_midnight = "5"
print("There are "+time_until_midnight+" hours until midnight")

Correct Answer

time_until_midnight = "5"
print("There are " + time_until_Midnight + " hours until midnight")

Explanation

There is a typo in the last line, it should be time_until_midnight not time_until_Midnight. Because when the name of the variable was used it was not spelt the same, you will get a name error.
