that's the thing, i'm new in all of this and wathever key i try to write i always get an error "SyntaxError: invalid character '“' (U+201C)"
so i wondered what i could use as a key, because i keep getting this and an error that specify what's the problem
"File "/home/user/xor_file.py", line 2
KEY = “10110111” no matter what i try either binary (here) or letters i don't know what key i should use

Do you know that it's a pythons script, right? You need to run it using python2.

i'm a real dumbass, thank's for taking your time man, really . I kept running it wrongly ...
