What is the result of the command 'print(' , .split())'?

The command print(' , .split()) returns [''] because of how the split method works in Python. When called without any arguments, the split() method divides the string at whitespace by default. However, if the string consists solely of whitespace (as in this case, two spaces followed by a comma and then another space), the split operation does not create any substrings; rather, it results in an empty string.

Here’s a breakdown of the process:

1. The original string is ' ,', which contains two spaces and a comma.

2. The split() method, when applied to a string that contains only whitespace or is empty, will yield a list with one element: an empty string. This is because it splits the string at whitespace and since there is nothing else but spaces, it results in one empty part.

This behavior is crucial for understanding how string manipulation works in Python, especially when dealing with whitespace. Consequently, the result of the split() method in this situation is a list containing a single empty string, which is why the answer is [''].
