为什么Hex()函数返回字符串而不是int hex? [英] Why Does Hex() Function returns a string instead an int hex?

问题描述

我不知道为什么Hex函数返回的字符串类似于'0x41'而不是0x41

I dont know why Hex function returns a string like '0x41' instead 0x41

我需要将ASCII值转换为十六进制.但是我想要0x INT格式，而不是'0x'字符串.

I need to convert an ASCII value into a hex. But i want in 0x INT format, not into a '0x' string.

ascii = 360
hexstring = hex(ascii)
hexstring += 0x41  # i cant do this because hexstring is a string not a int hex

我如何获取整数十六进制? 谢谢

How i can get a int hex?? thanks

推荐答案

没有int hex对象.只有替代语法可以创建整数:

There is no int hex object. There is only an alternative syntax to create integers:

>>> 0x41
65

您也可以使用0o1010来获得相同的值.或使用0b1000001以二进制形式指定它；它们都是与Python完全相同的数字值；它们都是用于在代码中指定整数值的不同形式.

You could have used 0o1010 too, to get the same value. Or use 0b1000001 to specify it in binary; they are all the exact same numeric value to Python; they are all just different forms to specify an integer value in your code.

只需将ascii保留为整数，然后将您的十六进制表示法值相加即可:

Simply keep ascii as an integer and sum your hex notation values with that:

>>> ascii = 360
>>> ascii += 0x41
>>> ascii
425

hex()生成可由Python程序以相同方式解释的字符串，通常在调试代码或快速演示输出时使用(但如果要生成最终用户输出，则应使用format(number, 'x')不带0x前缀).不需要使用整数.

hex() produces a string that can be interpreted by a Python program in the same manner, and is usually used when debugging code or quick presentation output (but you should use format(number, 'x') if you want to produce end-user output without the 0x prefix). It is not needed to work with integers.
