# Python NumPy: Sort an along the first, last axis of an array

## Python NumPy: Array Object Exercise-29 with Solution

Write a Python program to sort an along the first, last axis of an array.
Sample array: [[2,5],[4,4]]

Sample Solution:-

Python Code:

``````import numpy as np
a = np.array([[4, 6],[2, 1]])
print("Original array: ")
print(a)
print("Sort along the first axis: ")
x = np.sort(a, axis=0)
print(x)
print("Sort along the last axis: ")
y = np.sort(x, axis=1)
print(y)
```
```

Sample Output:

```Expected Output:
Original array:
[[4 6]
[2 1]]
Sort along the first axis:
[[2 1]
[4 6]]
Sort along the last axis:
[[1 2]
[4 6]]
```

Python Code Editor:

```import numpy as np
a = np.array([[4, 6],[2, 1]])
print("Original array: ")
print(a)
print("Sort along the first axis: ")
x = np.sort(a, axis=0)
print(x)
print("Sort along the last axis: ")
y = np.sort(x, axis=1)
print(y)```
