How to input ordered array in python

You can use the following methods to sort Python arrays: 1. sort() method: Sort the list in place and print it in ascending order. 2. sorted() function: Creates and returns a new sorted list. 3. Numpy's argpartition() method: Partitions the array into specified parts, where the first k elements are arranged in ascending order.

How to use Python to input an ordered array

Use the sort() method:

The sort() method sorts the elements in the list in ascending order. So, to input a sorted array, you create a list and then sort it using the sort() method.

numbers = [5, 2, 8, 3, 1]
numbers.sort()
print(numbers)  # 输出：[1, 2, 3, 5, 8]

Using the sorted() function:

The sorted() function creates a new list in which the elements are sorted in ascending order.

numbers = [5, 2, 8, 3, 1]
sorted_numbers = sorted(numbers)
print(sorted_numbers)  # 输出：[1, 2, 3, 5, 8]

Use Numpy's argpartition() method:

The argpartition() method partitions the array into specified k parts, where the first k elements are sorted in ascending order of.

import numpy as np

numbers = np.array([5, 2, 8, 3, 1])
partition_index = np.argpartition(numbers, kth=2)
sorted_numbers = numbers[partition_index[:3]]
print(sorted_numbers)  # 输出：[1, 2, 3]
