Though in some cases, you might need the separation to occur based on not just one but multiple delimiter values. When there are … You may define a range of characters a regular expression can match by providing them within square brackets.eval(ez_write_tag([[250,250],'delftstack_com-banner-1','ezslot_1',110,'0','0'])); Therefore when specifying the pattern of our regular expression, we can simply provide a semicolon and comma within square brackets and an additional space [;,] which would result in the regular expression being matched by parts of a string with exactly [a semicolon OR comma] and a trailing space.eval(ez_write_tag([[300,250],'delftstack_com-medrectangle-4','ezslot_10',120,'0','0'])); Prior mentioned basic expression was limited to a hardcoded set of separators.

Pandas provide a method to split string around a passed separator/delimiter. Note : A delimiter is a sequence of one or more characters used to specify the boundary between separate, independent regions in plain text or other data streams. Is this a good way of implementing it (more performance)? I think what I want to do is a fairly common task but I’ve found no reference on the web. 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.   |  Facebook page If no separator is specified, then the split() method splits the string based on whitespace; The maxsplit number specifies the maximum number of Split.
