## NumPy – Divide all elements in array by a constant

Dividing a NumPy array by a constant is as easy as dividing two numbers. To divide each and every element of an array by a constant, use division arithmetic operator `/`

. Pass array and constant as operands to the division operator as shown below.

`b = a / c`

where `a`

is input array and `c`

is a constant. `b`

is the resultant array.

## Example

In the following python example, we take an array in `a`

, and divide this array by a constant `3`

. The resulting array is stored in `b`

, and print to the standard output.

**Python Program**

```
import numpy as np
#2D array
a = (np.arange(8)*2).reshape(2,4)
#print array
print("The array\n",a)
#divide all the elements of array by constant
b = a / 3
print("\nAfter dividing by a constant\n",b)
```

Run **Output**

### Summary

In this Numpy Tutorial of Python Examples, we learned how to divide elements in a numpy array by a constant.
