So escape sequences are formed using two things: the first is a backslash (\\), and the second is the set of one or more characters following that backslash (\\). A sequence is just a set of two or more characters and an escape where the sequence begins with a backslash (\\) and other characters in the set follow that backslash.Īn escape sequence is a sequence of characters that, when used inside a character or string, does not represent itself but is converted into another character or series of characters. But if you want to escape a specific set of characters then use this lambda function: > escape lambda s, escapechar, specialchars: ''.join(escapechar + c if c in specialchars or c escapechar else c for c in s) > s rawinput() I'm 'stuck. It is used in representing certain whitespace characters: t. Python Escape Characters Python Glossary Escape Characters To insert characters that are illegal in a string, use an escape character. If you want to escape a string for a regular expression then you should use re.escape(). So here comes the role of escape sequences.įirstly, understand sequences. In Python strings, the backslash is a special character, also called the escape character. Suppose you have the string containing a double backslash (\\\\), and you want to print the string with a double backslash, but it is impossible to print it directly. An escape character is a backslash followed by the character you want to insert. String quotes can be escaped with a backslash, but the backslash remains in the string for example, r is a valid string literal consisting of two characters. Introduction to Escape Sequence in Python To insert characters that are illegal in a string, use an escape character. ![]() ![]() ![]() This character serves as an escape sequence initiator, and every character (one or more) following it is considered an escape sequence. In the escape sequence, a character is preceded by a backslash (\) followed by the character you want to represent for the new line. An escape sequence is a sequence of characters that, when used inside a character or string, does not represent itself but is converted into another character or series of characters that may be difficult or impossible to express directly, like newline (\n), tab (\t), and so on.
