Program to display elements inside a list using for and while loop

This program demonstrate how to display elements inside a list using for and while loop

Create a list of numbers

num = [1,2,3,4,5,6,7,8,9]

Calculate number of elements in a list using len() function

l = len(num)
print('Number of elements in a list:',l)

Create a variable i and assign 0 value to it

i = 0

Using while loop to display each element of a list

while i < l:
    print(num[i])
    i+=1

Using for loop to display each elements of a list

for n in num:
    print(n)

Output

Number of elements in a list: 9
