Two Types of Division

In Python 2, when we divide two integers, we get an integer as a result. When the quotient is a whole number, this works fine:

```
quotient = 6/2
# the value of quotient is now 3, which makes sense
```

However, if the numbers do not divide evenly, the result of the division is truncated into an integer. In other words, the quotient is rounded down to a whole number. This can be surprising when you expect to receive a decimal and you receive a rounded-down integer:

```
quotient = 7/2
# the value of quotient is 3, even though the result of the division here is 3.5
```

To yield a float as the result instead, programmers often change either the numerator or the denominator (or both) to be a float:

```
quotient1 = 7./2
# the value of quotient1 is 3.5
quotient2 = 7/2.
# the value of quotient2 is 3.5
quotient3 = 7./2.
# the value of quotient3 is 3.5
```

An alternative way is to use the `float()`

method:

```
quotient1 = float(7)/2
# the value of quotient1 is 3.5
```

You have come home from the grocery store with 100 cucumbers to split amongst yourself and your 5 roommates (6 people total).

Create a variable `cucumbers`

that holds `100`

and `num_people`

that holds `6`

.

Create a variable called `whole_cucumbers_per_person`

that is the integer result of dividing `cucumbers`

by `num_people`

.

Print `whole_cucumbers_per_person`

to the console.

You realize that the numbers don’t divide evenly and you don’t want to throw out the remaining cucumbers. Create a variable called `float_cucumbers_per_person`

that holds the float result of dividing `cucumbers`

by `num_people`

.

Print `float_cucumbers_per_person`

to the console.
