4.7: Time Machine Your time machine is capable of going forward in time up to 24 hours. The machine is configured to jump ahead in minutes. To enter the proper number of minutes into your machine, you would like a program that can take a start time (in hours, minutes, and a Boolean indicating AM or PM) and a future time (in hours, minutes, and a Boolean indicating AM or PM) and calculate the difference in minutes between the start and future time. A time is specified in your program with three variables: int hours, minutes; bool isAM; for example, to represent 11:50 PM, you would store: hours = 11,minutes = 50,isAM = false This means that you need six variables to store a start and future time. Write a program that allows the user to enter a start time and a future time. Include a function named computeDifference that takes the six variables as parameters that represent the start time and future time. Your function should return, as an int, the time difference in minutes. for example,…

5.21 In Python: 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 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some 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 following function. The function should return true if the input year is a leap year and false otherwise.def is_leap_year(user_year)

2.11 LAB: Pizza party Given the number of people attending a pizza party, output the number of needed pizzas and total cost. For the calculation, assume that people eat 2 slices on average and each pizza has 12 slices and costs $14.95. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f'Cost: ${cost:.2f}') Hint: Use the ceil() function from the math module to round up the number of pizzas so that enough pizzas are ordered. Ex: If the input is: 4 the output is: Pizzas: 1 Cost: $14.95 411776.2636306.qx3zqy7 LAB 2.11.1: LAB: Pizza party ACTIVITY main.py Type your code here. 1 import math 2 3 4 0/10 Load default template...
7.7 LAB: Count characters Write a program whose input is a string which contains a character and a phrase, and whose output indicates the number of times the character appears in the phrase. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. n is different than N. Ex: If the input is: n Nobody the output is: 0 n's python please explain so i can understand
