Write python file with various asci codes

I would like to write a python file containing four bytes:

• A space
• A tab
• A carriage return
• A newline

I’m not able to write it as:

open('file.txt', 'w').write(' \t\r\n')

As for whatever reason it’s converting the \r into a \n. How would I then write this as the asci codes themselves? that is:

NEWLINE = 10
CARRIAGE = 13
SPACE = 32
TAB = 9
open('file.txt','wb').write(bytearray([SPACE, TAB, CARRIAGE, NEWLINE]))

>Solution :

Open the file in binary mode and write a byte string.

open('file.txt', 'wb').write(b' \t\r\n')
