I have a string that needs to be split based on the occurrence of a ","(comma), but need to ignore any occurrence of it that comes within a pair of parentheses.
For example, B2B,(A2C,AMM),(BNC,1NF),(106,A01),AAA,AX3
Should be split into
B2B,
(A2C,AMM),
(BNC,1NF),
(106,A01),
AAA,
AX3

You do not only have to use literal strings for splitting strings into an array with the split method. You can use regex as breakpoints that match more characters for splitting a string.
split(String regex) method splits this string around matches of the given regular expression. This method works in the same way as invoking the method i.e split(String regex, int limit) with the given expression and a limit argument of zero. Therefore, trailing empty strings are not included in the resulting array.
If you want to split a string that matches a regular expression (regex) instead of perfect match, use the split() of the re module. In re. split() , specify the regex pattern in the first parameter and the target character string in the second parameter.
The split() method splits a string into an array of substrings. The split() method returns the new array. The split() method does not change the original string. If (" ") is used as separator, the string is split between words.
