I want to split a string containing square brackets '[]', however, when I call re.split in the re package:

re.split('[]',string)

, it turns out to be: 're.error: unterminated character set at position 0'enter code here.

CodePudding user response：

[ and ] are meaningful characters in regular expressions. They allow for the creation of sets of characters to match.

For instance, to match 'a', 'b', or 'z': [abz].

To match these characters literally escape them with backslashes. Using a raw string (prefixed with r) removes the need to escape the backslashes with backslashes.

re.split(r'\[\]',string)
