Meaning of 0x and \x in python hex strings?
提问by TheMeaningfulEngineer
I'm doing some binary operations which are often shown as hex-es. I have seen both the 0xand \xas prefixes.
我正在做一些通常显示为十六进制的二进制操作。我已经看到了0x和\x作为前缀。

0xis used for literal numbers. "\x"is used inside strings to represent a character
0x用于文字数字。"\x"用在字符串内部来表示一个字符
>>> 0x41
65
>>> "\x41"
'A'
>>> "\x01" # a non printable character
'\x01'
回答by Euler
0x follows number, means HEX number
0x 跟在数字后面，表示十六进制数字
\x follows number, means HEX ascii characters
\x 跟随数字，表示十六进制 ascii 字符
check it here: ascii table
在这里检查： ascii表
