| bytes, or bytearray instance representing an integer literal in the | given base. The literal can be preceded by '+' or '-' and be surrounded | by whitespace. The base defaults to 10. Valid bases are 0 and 2 - 36. | Base 0 means to interpret the base from the string as an ...
Base 0 means to interpret exactly as a code literal, so that the actual base is 2, 8, 10, or 16, and so that int('010', 0) is not legal, while int('010') is, as well as int('010', 8). hex(x) Convert an integer number to a hexadecimal string. The result is a valid ...
| Convert a number or string to an integer, or return 0 if no arguments | are given. If x is a number, return x.__int__(). For floating point | numbers, this truncates towards zero. | | If x is not a number or if base is given, then x must be a string, | bytes, or ...
decode(hex_val, "hex") print(byte_val) This program decodes the hex_val string using the codecs.decode() function with the encoding argument set to 'hex'. This means it will interpret the input string as a hexadecimal value and convert it to bytes.Output:...
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 Python expression. If x is not a Python int object, it has to define an __index__() method that ...

In Python 2, thecodecs.decode()returns a string as output; in Python 3, it returns a byte array. The below example code demonstrates how to convert a hex string to ASCII using thecodecs.decode()method and convert the returned byte array to string using thestr()method. ...
