# How to Calculate a Percentage in Python

To get a percentage of two numbers in Python, divide them using the division operator (`/`

) then multiply the result by 100 using the Python multiplication operator (`*`

).

To demonstrate this, let's get the percentage of 3 out of 9 using Python.

```
percent = 3 / 9 * 100
print(percent)
```

```
33.33333333333333
```

## Python Percentage Function

If you need to get percentages many times in your program, it may be worth creating a small helper function.

```
def getPercent(first, second, integer = False):
percent = first / second * 100
if integer:
return int(percent)
return percent
print(getPercent(3, 9))
```

```
33.33333333333333
```

With the above function, to get an integer back pass `True`

as the third argument.

```
def getPercent(first, second, integer = False):
percent = first / second * 100
if integer:
return int(percent)
return percent
print(getPercent(3, 9, True))
```

```
33
