What is the method for creating arrays in Python?

There are various ways to create arrays in Python, below are some common methods listed.

1. Using list comprehension:

arr = [x for x in range(10)]  # 生成一个包含0到9的数组

1. Use the range() function:

arr = list(range(10))  # 生成一个包含0到9的数组

1. Utilizing the numpy library:

import numpy as np

arr = np.array([1, 2, 3, 4, 5])  # 生成一个包含1到5的numpy数组

arr = np.zeros(5)  # 生成一个包含5个0的numpy数组

arr = np.ones(5)  # 生成一个包含5个1的numpy数组

arr = np.arange(10)  # 生成一个包含0到9的numpy数组

1. Generate a random array using the random library.

import random

arr = [random.randint(1, 10) for _ in range(5)]  # 生成一个包含5个1到10之间随机整数的数组

Here are some common methods for generating arrays, choose the one that best suits your specific needs.
