Python中进制转换函数的使用 关于Python中几个进制转换的函数使用方法,做一个简单的使用方法的介绍,我们常用的进制转换函数常用的就是int()(其他进制转换到十进制).bin()(十进制转换到二进制).oct()(十进制转换到八进制).hex()(十进制转换到十六进制). 下面我们逐个说下每个函数的用法. bin bin()函数,是将十进制的数字转换成二进制的数字.其中bin()函数中传入的是十进制的数字,数据类型为数字类型. v = 18 num = bin(v) print(num)
2.1 Built-in Functions The Python interpreter has a number of functions built into it that are always available. They are listed here in alphabetical order. __import__( name[, globals[, locals[, fromlist]]]) This function is invoked by the import sta
