escaping - How to pass escape sequences to python's ord() function? -


i using python 3. using ord() function in script. if type ord('\xff') in console returns 255

is there way insert \xff (which stored in variable) ord() function without getting 

error: typeerror: ord() expected character, string of length 4 found

how ord('\xff') work? ord() doesn't read strings? whats reading then?

are receiving data user input? in case, meant read single character read literally string of size 4.

in [1320]: v = input() \xff  in [1321]: v out[1321]: '\\xff'

one workaround use ast.literal_eval:

in [1326]: import ast  in [1327]: v = ast.literal_eval('"{}"'.format(v))  in [1329]: ord(v) out[1329]: 255

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
