+#### 💡 Explanation:
+
+- It might appear at first that the default seperator for split is a single space `' '`, but as per the [docs](https://docs.python.org/2.7/library/stdtypes.html#str.split),
+    > If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns `[]`.
+    > If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, `'1,,2'.split(',')` returns `['1', '', '2']`). Splitting an empty string with a specified separator returns `['']`.
+- Noticing how the leading and trailing whitespaces are handled in the following snippet will make things clear,
+    ```py
+    >>> ' a '.split(' ')
+    ['', 'a', '']
+    >>> ' a '.split()
+    ['a']
+    >>> ''.split(' ')
+    ['']
+    ```
