Python Program To Print Average

-

 

In this post, we are going to write a python program to print get the input of data from the user and print its average.



General Idea :

The average of a set of data is the sum of the data and divided by the total number of data.





Pre-Requisites  :

  • Python Basics
  • For loop
Program :

n=int(input("Enter the  total number of numbers"))
sum1=0
for i in range(0,n):
    x=int(input("Enter number "))
    sum1=sum1+x
print("The Average is ",sum1/n)









Explanation :



1.First we are inputting the total number of data and storing that to variable 'n'. (Here in this case total number of numbers) 



2. Here we are initializing the variable (identifier) sum1 to 0, which would be used to find the sum of the data.



3. Here we are using for loop to input the data and find its sum. The start value is 0. The end value of the loop is n. That means it stops at n-1. The step value is 1 by default. Therefore the loop repeats n times.



4. This statement is written under the for loop created in the above step. That means this statement will repeat n times. Here we are inputting the data and storing that to x. Note x value will be changed when the loop enters the next step.



5. This statement is also written under the for loop. When this statement is executed the inputted data is added to the sum1. We already initialized sum1 to 0. As the loop enters a new step, as the user enters the new data which is stored to x, is added to sum1 successively.



6. This statement is written separately. Here we are printing the output. Average is the division of sum by the number of data. Here the sum is sum1 and the number of data is n in our case. Hence we wrote sum1/n.

Input/Output :










Thank you

Python Program to Print Fibonacci series - Codicaly

  In this post, we are going to write a program to print the Fibonacci series. General idea :               In mathematics, the  Fibonacci number  is a sequence , called the  Fibonacci sequence , such that each number is the sum of the two preceding ones, starting from 0 and 1. Like 0,1,1,2,3,5,8,13,21........... In this sequence, 0 and 1 are default numbers. Then the sum of 0 and 1 is 1.Then the sum of 1 and 1 is 2. Then the sum of 1 and 2 is 3. Then the sum of 2 and 3 is 5. And so on. Pre-Requisites : Python Basics Iteration ( For loop) Program : n=int(input("Enter the number of terms")) total=0 a=0 b=1 print(a) print(b) for i in range(0,n-2):     total=a+b     print(total)     a=b     b=total Explanation : 1.First we need to input the number of terms we need to print. Here we are doing that using print. 2.Here in these lines we are initializing the total to 0, a to 0, and b to 1. 'a' is the...

Python - Program to find the given number is a prime or composite number

  In this post, we are going to check whether an inputted number is a prime number or a composite number. What is a Prime number or a Composite number ?     A prime number is a number that has only two factors i.e, 1, and the number itself.  A composite number is a number that has more than two factors. A number is said to factor that when it divides the other number it leaves no remainder.  Generally, the factors lie between 1 and the number itself. Pre-requisites : Python introduction List concept Conditional statements  Program :  a=int(input("Enter the integer:")) list1=[] # empty list for factors for i in range(1, a+1):     if (a%i==0):         list1.append(i) if len(list1)== 2:     print("The given number ",a," is a prime number.") else :     print("The given number ",a," is a composite number.") Explanation :    1. First, we need to input the integer that we need to find is prime o...
