bin(int('1'+hex_str, 16))[3:] #含有前导0 # 结果 '0000000011111110' bin(int(hex_str, 16))[2:] #忽略前导0 # 结果 '11111110' 1. 2. 3. 4. 5. 二进制字符串转成16进制字符串 bin_str='0b0111000011001100' hex(int(bin_str,2)) # 结果 '0x70
英文文档:hex(x)Convert an integer number to a lowercase hexadecimal string prefixed with “0x”, for exampleIf x is not a Python int object, it has to define an index() method that returns an integer.说明: 1. 函数功能将10进制整数转换成16进制整数。>>> hex(15) '0xf' >>> hex(16)...
signed:是否使用二进制补码,如果 signed 为False并且给出的是负整数,则会引发OverflowError。默认 False @classmethodfrom_bytes(bytes,byteorder='big',*,signed=False) -> int注意这是一个类方法!(classmethod)to_bytes 的逆过程,参数含义相同。 as_integer_ratio(),is_integer()存在的意义是兼容 float 里的同...
