int('10') ==> 10 16进制字符串: int('10', 16) ==> 16 # 或者 int('0x10', 16) ==> 16 字节串to整数 使用网络数据包常用的struct,兼容C语言的数据结构 struct中支持的格式如下表 Format C-Type Python-Type 字节数 备注 x pad byte no value 1 c char string of length 1 1 b signed c...
最后,我们可以使用print()函数将二进制字符串打印出来。 print(binary_string) 1. 完整代码示例 下面是完整的代码示例,展示了如何将字节数据转换为二进制字符串。 byte_data=b'Hello World'binary_string=bin(int.from_bytes(byte_data,byteorder='big'))binary_string=binary_string[2:]print(binary_string) 1...

Similarly, the int() function to convert a binary to its decimal value. The int() function takes as a second argument the base of the number to be converted, which is 2 in the case of binary numbers. a = 79 # Base 2(binary) bin_a = bin(a) print(bin_a) print(int(bin_a, 2...
