For loop in Python||Part-2

Write a program to display table for given number in Python 

n=int(input('enter number'))

for i in range(1,11):

    t=n*i

    print(n," * ",i," = ",t)

 

§  Write a program Calculate the sum and average of first n natural numbers.

n = int(input("Enter Number to calculate sum and avg of first n natural number"))

sum = 0

for num in range(1, n+1):

    sum = sum+num

print("SUM of first ", n, "numbers is: ", sum )

avg=sum/n

print("Average of first ", n, "numbers is: ", avg )

Output:

Enter Number to calculate sum and avg of first n natural number 5

SUM of first  5 numbers is:  15
Average of first  5 numbers is:  3.0

Write a program to display the sum first n even and odd number in Python 

n=int(input('enter number'))

esum=0

osum=0

for i in range(1,n+1):

    if i%2==0:

        esum=esum+i

    else:

        osum=osum+i

print('Sum of First ',n,'Even number = ',esum)

print('Sum of First ',n,'Odd number = ',osum)

Output:

enter number10

Sum of First  10 Even number =  30

Sum of First  10 Odd number =  25

§  Write a program to display the factor of a given number.

n=int(input('enter number'))

print('Factor of ',n,end='')

for i in range(1,n+1):

    if n%i==0:

        print(i,sep=',',end='')

Output:
enter number 6

Factor of  6 is 1,2,3,6

§  Write a program to find the factorial of a given number.

What is a factorial?

§  In maths, the factorial of a non-negative integer, is the product of all positive integers less than or equal to this non-negative integer.

For example:

5! = 5 * 4 * 3 * 2 * 1 = 120

4! = 4 * 3 * 2 * 1 = 24

n factorial” is “
n! = n * (n — 1) * (n — 2) *…* 2 * 1,” where ’n’ is a positive integer.

n=int(input('enter number'))

f=1

for i in range(1,n+1):

    f=f*i

print('factorial of',n,' is ',f)

Output:

enter number5

factorial of 5  is  120
