Question

Write a program that prints out a list of the integers from 1 to 20 and their squares and also count all the squared numbers that are divided by 5. The output should look like this: 1----1 2----4 3----9 And so on.. Total count of Squared number divisible by 5 is : 4​

Answer 1

Language:

Python

Program:

count=0

for i in range(1,21):

   print(f"{i} ---- {i * * 2}")

   count+=1 if i * * 2%5==0 else 0

   

print(f"Total count of Squared number divisible by 5 is: {count}")

Output:

1 ---- 1

2 ---- 4

3 ---- 9

4 ---- 16

5 ---- 25

6 ---- 36

7 ---- 49

8 ---- 64

9 ---- 81

10 ---- 100

11 ---- 121

12 ---- 144

13 ---- 169

14 ---- 196

15 ---- 225

16 ---- 256

17 ---- 289

18 ---- 324

19 ---- 361

20 ---- 400

Total count of Squared number divisible by 5 is: 4

Explanation:

• Count acts as a counter for numbers divisible by 5. i * * 2 returns the number raised tot he power of 2 and %5==0 checks if the number  when divided by 5 returns 0 or not. If yes counter increases by 1 if not then 0 is added.
• Using f with print makes it connect the text written within {} to variables outside. For example : a= 5, print(f"{a}"} will print 5.
