Class 11 CS Practical - 20

 

20 - Write a program in Python to input a number and determine the sum of the digits of that number.

n=int(input("Enter a number: "))

sum=0

while n>0:

    r=n%10

    n=n//10

    sum=sum+r

print("Sum of digits=",sum)

Output:

Enter a number: 145

Sum of digits= 10

Enter a number: 346

Sum of digits= 13

Class 11 CS Practical - 19

 

19 - Write a program in Python to display the first 'n' terms of a Fibonacci series. 

a=0

b=1

n=int(input("Enter the number of terms to be printed for fibonacci Series: "))

print(a, b,end=' ')

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

    c=a+b

    print(c,end=' ')

    a=b

    b=c

Output:

Enter the number of terms to be printed for fibonacci Series: 10

0 1 1 2 3 5 8 13 21 34
