使用Python内置函数:bin()、oct()、int()、hex()可实现进制转换。 先看Python官方文档中对这几个内置函数的描述: bin(x) Convert an integer number to a binary string. The result is a valid Pyth
所以如果你试图把它转换成整数，但用户输入了字母或单词，就会出现一个叫做ValueError的错误。
In Python, you can use a built-in function,bin()to convert an integer to binary. Thebin()function takes an integer as its parameter and returns its equivalent binary string prefixed with0b. An example of this is: binary=bin(16)print(binary) ...

struct.unpack('B', data):这里的参数B的含义是将C结构数据的unsigned char 类型转为python中的integer 这里得到的num是tuple类型,因此使用num[0]将数字取出。 foriinrange(size):data = binfile.read(1)num = struct.unpack('B', data)print(num[0]) ...
是否可以用bin()？不能！官方文档中很明确地指出：Convert an integer number to a binary string ...
https://docs.python.org/3/library/stdtypes.html#binaryseqdocs.python.org/3/library/stdtypes.html#binaryseq Since bytes objects are sequences of integers (akin to a tuple), for a bytes objectb,b[0]will be an integer, whileb[0:1]will be a bytes object of length 1. (This contras...
