Q3. Use triple quotes to enclose a block of comments.

total = 0

Q5. Even numbers between 1 and 10 inclusive and display the result:
total = 0
for banana in range(2,11,2):
total = total + banana
print("The total is:", total)
Q6. To add up the even numbers between 1 and 1 000 000 and display the result:

Q8. Write a program to print out the numbers that are divisible by 5 between 1 and a 100 inclusive,

if num%5==0:
print(num)
Q9 - Q10 . A program to print out the numbers that are divisible by 17 between 1 and a 200 inclusive and also prints out how many numbers were divisible by 17:
print('\n')
count=0
for num in range(1,201):
if num%17==0:
print(num)
count+=1
print('\n')
print(count, 'numbers were divisible by 17.')
