Modulo

Python offers a companion to the division operator called the modulo operator. The modulo operator is indicated by `%`

and gives the remainder of a division calculation. If the number is divisible, then the result of the modulo operator will be 0.

```
# Prints 4 because 29 / 5 is 5 with a remainder of 4
print(29 % 5)
# Prints 2 because 32 / 3 is 10 with a remainder of 2
print(32 % 3)
# Modulo by 2 returns 0 for even numbers and 1 for odd numbers
# Prints 0
print(44 % 2)
```

Here, we use the modulo operator to find the remainder of division operations. We see that `29 % 5`

equals 4, `32 % 3`

equals 2, and `44 % 2`

equals 0.

The modulo operator is useful in programming when we want to perform an action every nth-time the code is run. Can the result of a modulo operation be larger than the divisor? Why or why not?

You’re trying to divide a group into four teams. All of you count off, and you get number 27.

Find out your team by computing 27 modulo 4. Save the value to `my_team`

.

Print out `my_team`

. What number team are you on?

Food for thought: what number team are the two people next to you (26 and 28) on? What are the numbers for all 4 teams?
