Write a program that works out whether if a given number is an odd or even number.
Even numbers can be divided by 2 with no remainder.
e.g. 86 is even because 86 ÷ 2 = 43
43 does not have any decimal places. Therefore the division is clean.
e.g. 59 is odd because 59 ÷ 2 = 29.5
29.5 is not a whole number, it has decimal places. Therefore there is a remainder of 0.5, so the division is not clean.
The modulo is written as a percentage sign (%) in Python. It gives you the remainder after a division.
e.g.
6 ÷ 2 = 3 with no remainder.
6 % 2 = 0
5 ÷ 2 = 2 x 2 + 1, remainder is 1.
5 % 2 = 1
14 ÷ 4 = 3 x 4 + 2, remainder is 2.
14 % 4 = 2
Warning your output should match the Example Output format exactly, even the positions of the commas and full stops.
43
This is an odd number.
94
This is an even number.
e.g. When you hit run, this is what should happen:
- All even numbers can be divided by 2 with 0 remainder.
- Try some using the modulo with some odd numbers e.g.
3 % 2
5 % 2
7 % 2
Then try using the modulo with some even numbers e.g.
4 % 2
6 % 2
8 % 2
See what's in common each time.
