As mentioned on the Wikipedia page, Regular Expressions use IEEE POSIX as the standard for its syntax. By default the max is the upper limit of an integer, i.e., the default value does not limit the splits. Write a Python program to split a string with multiple delimiters. In case you want to refrain from using Regular Expressions or do not need to introduce new modules to the project just for the sake of splitting a string, you can use replace() and split() methods present in the string module itself in sort of a hacky way to achieve the same result.eval(ez_write_tag([[300,250],'delftstack_com-large-leaderboard-2','ezslot_8',111,'0','0'])); Here first off, we replace all occurrences of a semicolon followed by a space (; ) within the string with our other delimiter which is a comma followed by a space (, ).
