Lists, generally, are homogeneous sequences. In the above case, we can use a list to store records of multiple employees where each employee record is a tuple. Thus, we can add and remove employees from the list
This is sufficient when you have a one-dimensional list or tuple, but not enough when you have a multi-dimensional list. Unlike the NumPy array, a list or tuple can have any number of elements in a row. You can have 3 items in the first row, then 2 items in the next. For example...

Then, all you need to do is to check if any element in the .parts tuple is in the list of directories to skip.You can check if any two iterables have an item in common by taking advantage of sets. If you cast one of the iterables to a set, then you can use the .isdisjoint(...
(In the admin’s case, this is the submit_row tag.) These sorts of tags are called “inclusion tags”. Writing inclusion tags is probably best demonstrated by example. Let’s write a tag that outputs a list of choices for a given Poll object, such as was created in the tutorials. ...
