How can I get it to divide decimals without it crashing

Question

The program works fine with whole numbers, as soon as I enter a decimal like 2.5 it crashes.

CLASS = str(input("What is the name of your class: "))

HOURS = int(input("How many hours a week do you spend in {}:".format(CLASS)))

number = HOURS*2

print("You should study for {}:" .format(number))

def study():

class_name = str(input("\nWhat is the name of your class: "))

hours_in_class_per_week = float(input(f"How many hours a week do you spend in your {class_name} class: "))

hours_to_study_per_week = 2 * hours_in_class_per_week

print(f"You should study for {hours_to_study_per_week} hours/week in your {class_name} class.\n")

def main():

study()

if __name__ == '__main__':

main()

# =================================================

# OUTPUT

# =================================================

# What is the name of your class: Python

# How many hours a week do you spend in your Python class: 12.5

# You should study for 25.0 hours/week in your Python class.

The HOURS variable has an int() surrounding it. So it expects you to give it something that it can turn into an integer. It cannot turn "2.5" (the string) into an integer, put it can turn it into a float. So you can change the int() into float, and everything should work.

Note: int() also has a feature where it rounds down floats. So if you have int(2.5) you get 2. Put it cannot do this with strings. So if you have int("2.5") it will crash and give you the error you are seeing. If you want this behavior, you can convert the string into a float before converting it into an int. for example int(float("2.5")) won't crash, but it will have that round down behavior and convert "2.5" into 2
