## NumPy: Array Object Exercise-155 with Solution

Write a NumPy program to check whether a Numpy array contains a specified row.

Sample Solution:

Python Code:

``````import numpy as np
num = np.arange(20)
arr1 = np.reshape(num, [4, 5])
print("Original array:")
print(arr1)
print([0, 1, 2, 3, 4] in arr1.tolist())
print([0, 1, 2, 3, 5] in arr1.tolist())
print([15, 16, 17, 18, 19] in arr1.tolist())
```
```

Sample Output:

```Original array:
[[ 0  1  2  3  4]
[ 5  6  7  8  9]
[10 11 12 13 14]
