python - Convert escape characters in strings (like "\\n" - two characters) into ASCII character (newline) -

my program got string command line arguments, contains many escapes characters.

./myprog.py "\x41\x42\n" 

when print "sys.argv[1]". got on screen:

\x41\x42\n 

is there simple way program print instead:

ab[newline] 

try passing argument in following way:

./myprog.py $'\x41\x42\n' 

the $'...' notation allowed used \x00-like escape sequences constructing arbitrary byte sequences hexadecimal notation.

another way fix @barak suggested here -- converting hex characters. depends on find easy you.
