help(max) 输出: Help on built-in function max in module builtin: max(…) max(iterable[, key=func]) -> value max(a, b, c, …[, key=func]) -> value 在单个可迭代参数中,返回其最大的项。使用两个或多个参数,返回最大的参数。 而内建模块则包含一些额外的函数。例如,为了得到一个数字...
>>> 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...
Here, we imported amathmodule to use the library functionssqrt()andpow(). More on Python Functions User Defined Function Vs Standard Library Functions In Python, functions are divided into two categories: user-defined functions and standard library functions. These two differ in several ways: User...
Themathmodule implements many of the IEEE functions that would normally be found in the native platform C libraries for complex mathematical operations using floating point values, including logarithms and trigonometric operations. Special Constants¶ Many math operations depend on special constants.mathin...
