All of this above might be good and dandy, but how and where do kids actually write code like the examples above to create programs? Interpreters allow computers to break down and understand programming languages like Python, similar to dictionaries. When a program is run, kids will see a ne...
Basicsare code examples that show you how to perform the essential operations within a service. Actionsare code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related ...
You’ve come a long way now, having figured out how to create all kinds of decorators. You’ll wrap it up, putting your newfound knowledge to use by creating a few more examples that might be useful in the real world.Slowing Down Code, RevisitedAs noted earlier, your previous ...
As an experienced programmer, you may find some of the initial code examples very ugly in design. In fact, hopefully you do. As we continue to develop our script in this section, the script will hopefully grow into an elegant design you can appreciate. Let’s begin by starting with the ...

Something isFalseif it evaluates to0, the valueNone, an empty string, or an empty built-in data structure. This means all of these examples areFalse: Every other object in Python evaluates toTrue. Here are some examples of objects that areTrue: ...
范围是不可变的整数序列,通常用于for循环。 Ranges are immutable sequences of integers,and they are commonly used in for loops. 要创建一个范围对象,我们键入“range”,然后输入范围的停止值。 To create a range object, we type "range" and then we put in the stopping value of the range. 现在,我...

Many processes in nature involve randomness in one form or another. 自然界中的许多过程都以这样或那样的形式涉及随机性。 Whether we investigate the motions of microscopic molecules or study the popularity of electoral candidates,we see randomness, or at least apparent randomness, almost everywhere. 无...
