Expert Solution
Explanation

1) We have a string s = "abc-def ghi"

2) s.split() split the string s with space and generate below list

  • ['abc-def', 'ghi']

3) s.split("-") split the string s with "-" and generate below list

  • ['abc', 'def ghi']

4) split(s) generates an error NameError: name 'split' is not defined. split() function is only applied on string.

5) "-".split(s) splits the string "-" with string s("abc-def ghi"). Since string s doesn't exist in "-", it just produces list as below

  • ['-']

6) s.split("-") is a correct option as it generates list ['abc', 'def ghi']
