The most and easy approach is to use the split () method, however, it is meant to handle simple cases. By referring to this standard, we can administer several additional ways we may come about writing a regular expression that matches our use case. Since in this case string replace() method will have to be used multiple times to make multiple traverses on the string, it would ultimately cause undesired performance spikes easily avoidable using Regular Expressions. To split a string with multiple delimiters, use re.split() function. 2. maxis the maximum number of splits the string can be split into.
