以下函数都是在Built-in Functions里面 hex(x) Convert an integer number to a lowercase hexadecimal string prefixed with “0x”. If x is not a Python int object, it has to define an __index__() method that returns an integer bin(x) Convert an integer number to a binary string prefixed...
该程序将一个16进制字符串转换为字符串,并打印出转换结果。 defhex_to_string(hex_str):# 将16进制字符串转换为整数integer=int(hex_str,16)# 将整数转换为字符串string=chr(integer)returnstring hex_str="48656c6c6f"result=hex_to_string(hex_str)print(result)# 输出:Hello 1. 2. 3. 4. 5. 6....

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 ...

hex(x) Convert an integer number to a lowercase hexadecimal string prefixed with “0x”, for example If 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。
若将十进制的浮点数转化为二进制,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 prefixed with “0b”.(https://docs.python.org/3/library/functions.html#bin),还可以试试: 代码语言:javascript

is_integer() -> bool是否是一个整数(小数部分为 0)同样因浮点误差导致并不准确 hex() -> str转换成十六进制表示。对于有限浮点数,这种表示法将总是包含前导的0x和尾随的p加指数。这里有效数字部分是真正的十六进制,但指数的含义是以 2 为底的指数,且指数本身使用十进制表示的 ...
