math.log2(x) Return the base-2 logarithm of x. This is usually more accurate thanlog(x, 2). New in version 3.3. See also:int.bit_length()returns the number of bits necessary to represent an integer in binary, excluding the sign and leading zeros. math.log10(x) Return the base-10...
接着:导入math模块,使用help函数,参数为max获取帮助,输入help(max) 然后:查看帮助信息,本例中具体为 Help on built-infunction maxinmodule builtins: max(...) max(iterable,*[, default=obj, key=func]) ->value max(arg1, arg2,*args, *[, key=func]) ->value ...
math The math module has a new function, log2(), which returns the base-2 logarithm of x. (Written by Mark Dickinson in bpo-11888.) mmap The read() method is now more compatible with other file-like objects: if the argument is omitted or specified as None, it returns the bytes from...
math.gamma(x) Return the Gamma function at x. math.lgamma(x) Return the natural logarithm of the absolute value of the Gamma function at x. collections模块 Python拥有一些内置的数据类型,比如str,int, list, tuple, dict等, collections模块在这些内置数据类型的基础上,提供了几个额外的数据类型: ...
