Besides operators, Python provides you with a bunch of built-in functions for manipulating numbers. These functions are always available to you. In other words, you don’t have to import them to be able to use them in your programs.
but doing so is strongly discouraged as it is usually simpler to use import hooks (see PEP 302) to attain the same goals and does not cause issues with code which assumes the
clean data, and create visualizations. However, it can be difficult to learn how to use Python in Excel, especially if you are not familiar with Python. This article will introduce Python in Excel and provide you with some resources to help you learn more. ...

In this section, you’ll see how you can use the modulo operator to determine if a number is even or odd. Using the modulo operator with a modulus of 2, you can check any number to see if it’s evenly divisible by 2. If it is evenly divisible, then it’s an even number. ...

上述的代码存在了多种 import 风格,比如: 同一模块下分别导入的部分各占一行 同一模块下导入的部分只站一行 存在重复导入的情况 …… 针对以上存在的一些导入问题,要么我们就干脆每个导入的部分只占一行,要么就是来自同一模块下的导入部分都连接在一起。

To make use of the functions in a module, you’ll need to import the module with animportstatement. Animportstatement is made up of theimportkeyword along with the name of the module. In a Python file, this will be declared at the top of the code, under any shebang lines or general...
