Python - String Escape Sequences
Introduction
To embed a quote inside a string, precede it with a backslash.
Backslashes introduce special character codings known as escape sequences.
Escape sequences embed characters that cannot be typed on a keyboard.
The character \, and one or more characters following it in the string literal, are replaced with a single character in the resulting string.
The following code has a five-character string that embeds a newline and a tab:
s = 'a\nb\tc'
The two characters \n stand for a single character-the binary value of the newline character in your character set.
The sequence \t is replaced with the tab character.
Demo
s = 'a\nb\tc' print( s )
Result
To get how many actual characters are in this string, use the built-in len function.
It returns the actual number of characters in a string, regardless of how it is coded or displayed:
Demo
s = 'a\nb\tc' print( len(s) )
Result
