>>> help(conf_intf) Help on function conf_intf in module __main__: conf_intf(intf, ip, mask) 本函数可生产接口配置 >>> 此时,我们就可以用help内置函数来探索一下它了,这与我们help其它模块函数本质上是一样的。在自定义函数中,这种简短注释是被广泛推荐的,例如函数期望多少参数,各为什么类型的参数...

We’re going to import the math module by saying "import math". 该模块具有多个功能。 The module comes with several functions. 我们将演示其中的几个。 We’re just going to demonstrate a couple of them. 例如,如果我想使用pi的值,我会键入math.pi,Python会告诉我pi的值,3.14,依此类推。 For ex...

You will be introduced to the mechanics of dictionaries and then get practice using them in accumulation patterns, both to build a dictionary using the pattern as well as find the best, or worst, result using the pattern. WEEK 3 Functions and Tuples In week three you will be introduced to...
即update_wrapper 函数 可以把 被封装函数的 __name__、__module__、__doc__ 和 __dict__ 都复制到封装函数去。 该函数主要用于装饰器函数的定义中,置于包装函数之前。如果没有对包装函数进行更新,那么被装饰后的函数所具有的元信息就会变为包装函数的元信息,而不是原函数的元信息。 这个函数的主要用途是在...
Under this scheme, the name of the module's initialization function must match the name used in the Setup file, or you'll get linking errors when you rebuild Python. The name of the source or object file doesn't have to match the module name; the leftmost name is the resulting Python ...
In Python, we can use the dir() function to list all the function names in a module. For example, earlier we have defined a function add() in the module example. We can use dir in example module in the following way: print(dir(example)) ['__builtins__', '__cached__', '__do...
