如何在Python中将十六进制字符串转换为文本？你知道吗

我有一个十六进制字符串

0x3C503E3235206D4C206F662033204D2048436C207765726520616464656420746F203735206D4C206F6620302E3035204D2048436C2E20546865206D6F6C6172697479206F662048436C20696E2074686520726573756C74696E6720736F6C7574696F6E20202026656D73703B26656D73703B26656D73703B26656D73703B2020200D0A20202026656D73703B26656D73703B26656D73703B26656D73703B2020697320617070726F78696D6174656C792D

我想用Python把它转换成文本。我该怎么做？你知道吗

我试过这个

print(bytes.fromhex(xyz))

其中xyz是存储该字符串的变量，但我得到了这个错误

non-hexadecimal number found in fromhex() arg at position 1

Answer 1

只需从字符串的开头切掉“0x”。所以呢

print(bytes.fromhex(var[2:]))

将给予
