Python import statement enables the user to import particular modules in the corresponding program. It resembles the #include header_file in C/C++. As soon as the interpreter encounters the import statement in a particular code, it searches for the same in the local scope and imports the module...
In this video, you’ll take a deep dive into the import statement. So, what forms can the import statement take? In its simplest form, it’s like what you’ve already used in the previous video: import and then the module’s name. In that particular…

For example, we might want to implement a simple random sampling process. 为此,我们可以使用随机模块。 To this end, we can use the random module. 所以,我们的出发点是,再次导入这个模块,random。 So the starting point is, again, to import that module, random. 让我们考虑一个简单的例子,其中列表...
import statistics as st def describe(sample): return st.mean(sample), st.median(sample), st.mode(sample) In describe(), you take advantage of Python’s ability to return multiple values in a single return statement by returning the mean, median, and mode of the sample at the same time...

I’m first going to import the random library. 我首先要导入随机库。 So I type import random. 所以我输入import random。 Then we’ll use t
A function is a block of code that performs a specific task. In this tutorial, we will learn about the Python function and function expressions with the help of examples.
在Python中,类是面向对象编程(OOP)的核心概念之一,它提供了一种将数据和功能封装在一起的方式。 类(class)把数据与功能绑定在一起。创建新类就是创建新的对象类型,从而创建该类型的新实例。 类实例具有多种保持自身状态的属性。 类实例还支持(由类定义的)修改自身状态的方法。
