Special characters can be represented as backslash escape sequences.
Python displays them in \xNN hexadecimal escape notation, unless they represent printable characters:
S = 'A\nB\tC' # \n is end-of-line, \t is tab print( len(S) ) # Each stands for just one character print( ord('\n') ) # \n is a byte with the binary value 10 in ASCII # from w w w . jav a 2 s .c om S = 'A\0B\0C' # \0, a binary zero byte, does not terminate string print( len(S) ) print( S ) # Non-printables are displayed as \xNN hex escapes
