Question

PYTHON PROGRAMMING: DO NOT USE INPUT FUNCTION, use sys.argv (PLEASE TYPE OUT ANSWER)

Modify this program:

Write a program to calculate the bmi
getcategory(): takes the bmi as a parameter and returns the bmi category.

You are not allowed to change the two functions and you will use the same two functions as previously. Just modify the program so that it calculates the bmi and category for any number of pairs of height and weights. You must loop through the height and weights, calling the functions, for full credit. The error message should still work the same as in the previous assignment. If someone enters the wrong number of arguments (see below), a different error message appears. The output is shown below.

Input:

a) 65 120 70 170

b) 65 120 70

Output:

a) BMI: 19.97, and the category is normal.
BMI: 24.39, and the category is normal.

b) The wrong number of arguments provided.
