The program described above which calculates mean, median and standard deviations of all entered values is given below.
A program is a set of instructions that ensure that a predetermined or specific output is given by a computer.
The program labelled find_stas.py is given as follows:
# importing required libraries
import math
# creating a empty list named li
li = []
# iterate till while is true
while True:
# getting user input making it int and store it in inp
inp = int(input("Enter integer (0 to stop): "))
# checks if inp is equals to 0
if inp == 0:
# stop the loop
break
# append inp in li
li.append(inp)
n = len(li)
# calculating sum li using sum function then dividing by n and store it in mean
mean = sum(li) / n
# dividing n by 2 and store it in indexes
index = n // 2
# if n modulus n equals 2
if n % 2:
# sort the li and store the index position in median
median = sorted(li)[index]
# otherwise
else:
# store the result in media
median = sum(sorted(li)[index - 1:index + 1]) / 2
# declaring d variable with value 0
d = 0
# calculating variance and store it in variance
variance = sum((x - mean) ** 2 for x in li) / (n - d)
# standard deviation
sd = math.sqrt(variance)
# display the output with the value of mean, median and sd
print("Mean : {}\nStandard Deviation : {}\nMedian : {}".format(mean, median, sd))
