Question

programming in Python

1. The body mass index (BMI) is calculated as a person’s weight (in lb) times 720, divided by the square of the person’s height (in inches). A BMI in the range 19-25, inclusive, is considered healthy. Write a program that inputs people’s weight and height, then calculates a person’s BMI and print a message telling whether they are above, within, or below the healthy range.
2. A formula for computing Easter in the years 1982-2048, inclusive, is as follows: let a=year%19, b=year%4, c=year%7, d=(19a+24)%30, e=(2b+4c+6d+5)%7. The date of Easter is March 22+d+e (which could be in April). Write a program that inputs a year, verifies that it is in the proper range, and then prints out the date of that year.

Answer 1

weight = float(input("Enter weight in pounds: "))
height = float(input("Enter height in inches: "))
bmi = weight / (height ** 2)

print("BMI of the person is " + str(bmi))

if bmi < 19:
    print("Person is below healthy range.")
elif bmi <= 25:
    print("Person is in healthy range.")
else:
    print("Person is above healthy range.")

year = int(input('Enter year: '))
if year < 1900 or year > 2099:
    print('Error. Invalid year. Year should be between 1900 and 2099')
else:
    a = year % 19
    b = year % 4
    c = year % 7
    d = (19 * a + 24) % 30
    e = (2 * b + 4 * c + 6 * d + 5) % 7
    dateOfEaster = 22 + d + e
    if year in [1954, 1981, 2049, 2076]:
        dateOfEaster -= 7
    if dateOfEaster <= 31:
        print("Date of easter is March-" + str(dateOfEaster))
    else:
        print("Date of easter is April-" + str(dateOfEaster-31))
