Concept explainers

Max Function
Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.
Power Function
A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be…
Question

Can you use Python programming language to to this question?

Thanks

Pre-task Please write a program which asks the user for integer numbers. The program should keep asking for numbers until the user types in zero. Please type in integer numbers. Type in 0 to finish. Number: 5 Number: 22 Number: 9 Number: -2 Number: 0 Part 1: Count After reading in the numbers the program should print out how many numbers were typed in. The zero at the end should not be included in the count. You will need a new variable here to keep track of the numbers typed in. ... the program asks for numbers Numbers typed in 4 ... the program asks for numbers Numbers typed in 4 The sum of the numbers is 34 Part 2: Sum The program should also print out the sum of all the numbers typed in. The zero at the end should not be included in the calculation. The program should now print out the following: ... the program asks for numbers. Numbers typed in 4 Sample output The sum of the numbers is 34 The mean of the numbers is 8.5 Part 3: Mean The program should also print out the mean of the numbers. The zero at the end should not be included in the calculation. You may assume the user will always type in at least one valid non-zero number. Sample output ... the program asks for numbers Numbers typed in 4 The sum of the numbers is 34 The mean of the numbers is 8.5 Positive numbers 3 Negative numbers 1 1 # write your solution here Sample output Part 4: Positives and negatives The program should also print out statistics on how many of the numbers were positive and how many were negative. The zero at the end should not be included in the calculation. Sample output Sample output
