A dramatic theater has three seating sections, and it charges the following prices for tickets in each section: section A seats cost $20 each, section B seats cost $15 each, and section C seats cost $10 each. The theater has 300 seats in section A, 500 seats in section B, and 200 seats in section C. Design a program that asks for the number of tickets sold in each section and then displays the amount of income generated from ticket sales. The program should validate the numbers that are entered for each section.

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.
