Lists

Create a program that asks the user for 10 numbers  (floating point). Store those numbers in a list. Show to the user the total, average and standard deviation of those numbers.

import statistics
def totalsum (m):
    total = 0
    for indice in range(len(m)):
        total = total + m[indice]
    return total
def average (m):
    avg = total / 10.0
    return avg
def standevi (m):
    sd = statistics.stdev(l)
    return sd

l=[]
x = 0

while (x < 10):
    x = x + 1
    n = float(input(“Give me a number: “))
    l.append(n)
    total = totalsum(l)
    avg = average(l)

devi = standevi(l)

print (“No more values.”)
print (“Total sum: “, total)
print (“Average: “, avg)
print (“Stardard deviation: “, devi)

Factorial  Calculator

Create a program that asks the user for a non-negative integer (let’s call that number n) and display for them the value of n! (n factorial).

After showing them the answer, ask them if they would like to try another number (with a simple y/n response) and either ask again (for y) or quit the program and wish them a nice day (if they answered n).

    while(a > 1):

        a = a – 1
    return b
import sys
op=”y”
while (op==”y”):
    n=input(“Give me an integer number: “)
    if (n.isdigit() == False ):
        print (“Only integers”)
    else:
        n=int(n)
        f=factorial(n)
        if n < 0:
            print (“Negative numbers are not accepted.”)
        else:
            if n==0:
                print (“The factorial of 0 is 1.”)
            else:
                print(“The factorial of”,n,”is”,f)
    op=input(“Want to try again? (y/n): “)
if (op == “n”):
    print(“Have a nice day.”)
sys.exit()
