1)模块的定义 Python 模块(Module),是一个 Python 文件,以 .py 结尾,包含了 Python 对象定义和Python语句。 模块让你能够有逻辑地组织你的 Python 代码段。 把相关的代码分配到一个模块里能让你的代码更好用,更易懂。 模块能定义函数,类和变量,模块里也能包含可执行的代码。 2)模块的作用 - 最大

When Python imports a module calledhellofor example,the interpreter will first search for a built-in module calledhello. If a built-in module is not found, the Python interpreter will then search for a file namedhello.pyin #当前目录,然后in a list of directories that it receives from thesys...
1 #test.py 2 import sys 3 4 a=sys.argv[1] 5 print(a) 运行结果是: 得到的结果就是我们输入的参数what,看到这里你是不是开始明白了呢。 那我们再把代码修改一下: a=sys.argv[2:] 保存后,再从控制台窗台运行程序,这次多加几个参数,以空格隔开: test.py a b c d e f 得到的结果为[‘b’,...

Well, Python is somewhat of a sneaky snake when it comes to imports and managing modules. At runtime, themymodulemodule has its ownoswhich is imported into its own local scope in the module. Thus, if we mockos, we won’t see the effects of the mock in themymodulemodule. ...
