# Python NumPy: Find the set difference of two arrays

## Python NumPy: Array Object Exercise-20 with Solution

Write a Python program to find the set difference of two arrays. The set difference will return the sorted, unique values in array1 that are not in array2.

Sample Solution:-

Python Code:

``````import numpy as np
array1 = np.array([0, 10, 20, 40, 60, 80])
print("Array1: ",array1)
array2 = [10, 30, 40, 50, 70]
print("Array2: ",array2)
print("Unique values in array1 that are not in array2:")
print(np.setdiff1d(array1, array2))
```
```

Sample Output:

```Array1:  [ 0 10 20 40 60 80]
Array2:  [10, 30, 40, 50, 70]
Unique values in array1 that are not in array2:
[ 0 20 60 80]
```

Python Code Editor:

```import numpy as np
array1 = np.array([0, 10, 20, 40, 60, 80])
print("Array1: ",array1)
array2 = [10, 30, 40, 50, 70]
print("Array2: ",array2)
print("Unique values in array1 that are not in array2:")
print(np.setdiff1d(array1, array2))```
