Library Charges Program in Python

A library charges a fine for every book returned late. For first 5 days the fine is 50 paise, for 6-10 days fine is one rupee and above 10 days fine is 5 rupees. If you return the book after 30 days your membership will be cancelled. Write a program to accept the number of days the member is late to return the book and display the fine or the appropriate message.

This program is a simple program that calculates the fine amount for a library based on the number of days a book is overdue. The program takes an input from the user, the number of days the book is overdue and then uses conditional statements to determine the fine amount.

The program first checks if the number of days is greater than 0 and less than or equal to 5. If this condition is true, the fine amount is calculated by multiplying 0.50 with the number of days.
Next, the program checks if the number of days is greater than or equal to 6 and less than or equal to 10. If this condition is true, the fine amount is calculated by multiplying 1 with the number of days.
Then, the program checks if the number of days is greater than 10. If this condition is true, the fine amount is calculated by multiplying 5 with the number of days.
If the number of days is greater than 30, then the program will print that the membership would be cancelled.
If the input is invalid, the program will print "Invalid" as an output.
The program then prints the fine amount that the user needs to pay.

Source Code

days = int(input("Enter the Number of Days :"))
if (days>0 and days<= 5):
	amt = 0.50 * days
	print("Fine Amount Pay to Rs :", amt)
 
elif(days >= 6 and days <= 10):
	amt = 1 * days
	print("Fine Amount Pay to Rs :", amt)
 
elif (days > 10):
	amt = 5 * days
	print("Fine Amount Pay to Rs :", amt)
	if (days > 30):
		print("Your Membership would be Cancelled..")
else:
	print("Invalid")

Output

Enter the Number of Days :23
Fine Amount Pay to Rs : 115
