In howto/regex.rst I read: > '^' outside a character class will simply match the '^' character. Which looks wrong, '^' is the "begin anchor", it's a metacharacter that typically won't match '^'. I propose to simply remove the statement, if nobody finds a better idea. |

The caret has several meanings: * Generally, it is a beginning of string: r'^bol' * When MULTILINE is on, it is a beginning of line: r'^bos' * Escaped with a backslash, it is just a caret: r'a\^b' * Immediately after a left bracket, it inverts a character set: r'[^aeiou]' * Elsewhere in brackets, it is just a caret: r'[ab^d]' |
