Escape sequences let us embed byte codes in strings that cannot easily be type 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 object. The object has the binary value specified by th...

If you want to include either type of quote character within the string, then you can delimit the string with the other type. In other words, if a string is to contain a single quote, delimit it with double quotes and vice versa:
(the enclosing quotes could change), the two strings are equivalent. The string is enclosed in double quotes if the string contains a single quote and no double quotes, otherwise it is enclosed in single quotes. Theprint()function produces a more readable output, by omitting the enclosing ...

If you need to avoid embedding extra space in the string, use either concatenated single-line strings or a multi-line string with textwrap.dedent() to remove the initial space on each line:No: long_string = """This is pretty ugly. Don't do this. """...
