What line of code would produce this output: ['1','2','3','4']?1 point'1,2,3,4'.join(',')'1,2,3,4'.reverse(',')'1,2,3,4'.split(':')'1,2,3,4'.split(',')

To determine which line of code would produce the output ['1','2','3','4'], we need to analyze each option provided:

1. '1,2,3,4'.join(','): This code tries to join elements of an iterable with a comma, but since a string is not an iterable of strings for this function, this will result in an error.

2. '1,2,3,4'.reverse(','): The reverse method does not exist for strings in Python, as it is a list method. This will also result in an error.

3. '1,2,3,4'.split(':'): This will split the string at each occurrence of ':', but since there are no colons in the string, it would return the entire string as a single-element list: ['1,2,3,4']. Thus, it does not match the required output.

4. '1,2,3,4'.split(','): This line splits the string at each comma ',', resulting in the list ['1', '2', '3', '4'], which matches the desired output.

Based on this analysis:

Final Answer

The correct line of code that would produce the output ['1','2','3','4'] is:

'1,2,3,4'.split(',')
