You misunderstood what
\xhh
does in Python strings. Using\x
notation in Python strings is just syntax to produce certain codepoints.You can use
'\x61'
to produce a string, or you can use'a'
; both are just two ways of saying give me a string with a character with hexadecimal value 61, e.g. thea
ASCII character:>>> '\x61' 'a' >>> 'a' 'a' >>> 'a' == '\x61' True
The
\xhh
syntax then, is not the value; there is no\
and nox
and no6
and1
character in the final result.You should just write your string:
somestring = 'abcd' with open("test.bin", "wb") as file: file.write(somestring)
There is nothing magical about binary files; the only difference with a file opened in text mode is that a binary file will not automatically translate
\n
newlines to the line separator standard for your platform; e.g. on Windows writing\n
produces\r\n
instead.You certainly do not have to produce hexadecimal escapes to write binary data.
On Python 3 strings are Unicode data and cannot just be written to a file without encoding, but on Python the
str
type is already encoded bytes. So on Python 3 you'd use:somestring = 'abcd' with open("test.bin", "wb") as file: file.write(somestring.encode('ascii'))
or you'd use a byte string literal;
b'abcd'
.
python string写入二进制文件---直接web形式open file,再write string即可
