having a problem while calculating num_tickets ?

num_tickets = input("How many tickets would you like, {}? ".format(name)) num_tickets = int(num_tickets)

why do we need to put 'num_tickets' into 'int'. I believe it is already an 'int' because we assigning the integer value to it like 20,10,2,...so on. I also get confused with the term coerse.

When you receive a value through the input function it is stored as a string in the variable. You have to take that string and convert it to an integer in order to calculate the price; wrapping it in the int function converts the string to an int.

Hi gurveer, this is an important question.

You need to understand that the input method returns a String, not an integer. When you use input and type a number, this number will be stored as a String. To convert or coerce it to an integer, you need the int(...) method. Try this code in the workspace and type in a number ...

user_input = input("Your input: ")
print("The first input is {} ".format(type(user_input)))

input_to_integer = int(user_input)
print("After cenversion or coersion it is {}:".format(type(input_to_integer)))

Does this help to understand the topic?
