A function is a block of code that performs a specific task. Suppose we need to create a program to make a circle and color it. We can create two functions to solve this problem: function to create a circle function to color the shape Dividing a complex problem into smaller chunks makes...
对于py 文件,Python 虚拟机会先对py 文件进行编译产生PyCodeObject 对象,然后执行了co_code 字节码,即通过执行def、class 等语句创建PyFunctionObject、PyClassObject 等对象,最后得到一个从符号映射到对象的dict,自然也就是所创建的module 对象中维护的那个dict。 import 创建的module 都会被放到全局module 集合 sys.mo...

<class 'list'> ['Apple', 'Banana', 'Orange']访问列表：可以使用索引访问列表中的项。列表中的每个项都有一个与之关联的索引，具体取决于该项在列表中的位置。访问列表中的项的语法：#Access elements in the fruits listfruits = ['Apple', 'Banana',"Orange"]print(fruits[0]) #index 0 is the ...
Information can be passed into functions as arguments. Arguments are specified after the function name, inside the parentheses. You can add as many arguments as you want, just separate them with a comma. The following example has a function with one argument (fname). When the function is cal...
All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether you need subprocess or not, check out the section on deciding...
.py下包含多个classes或functions class or function的docstring 流程步骤 一般情况下,我们应该边开发边构建文档,开发过程中自己也经常会需要搜索已经实现的方法或类,因此“开发”和“构建文档”是同步进行的 首先会创建一个项目文件夹,假设叫XYZ,里面先创建几个文件: README.md requirements.txt experimental文件夹 note...
