How do you import the numpy library in Python?

To import the NumPy library in Python, you can use the import keyword. Typically, we import the NumPy library and assign an alias as np using the following syntax:

import numpy as np

This allows you to use ‘np’ as an alias to call functions and methods from the NumPy library. For example, you can create a NumPy array using ‘np.array()’.

Here are some examples:

import numpy as np
# 创建一个NumPy数组
arr = np.array([1, 2, 3, 4, 5])
print(arr)
# 使用NumPy函数操作数组
mean_value = np.mean(arr)
print("Mean:", mean_value)
# 使用NumPy方法操作数组
max_value = arr.max()
print("Max:", max_value)

By using the above import method, you can now access the functions in the NumPy library.
