To create a list in Python, you enclose your items in square brackets[], separating each item by a comma: python_list = ["dog",33, ["cat","billy"]] You can access, modify, and remove items in a list based on their position (index), and lists support various operations such as ...
Negative indexing is a useful feature in Python, allowing us to access elements from the end of a list without needing to know its length. So, with these print statements, we effectively retrieve the last and second-to-last elements in thecarslist. ...

In addition to this direct creation of arrays, both MATLAB and NumPy support a number of other methods to create arrays without explicitly specifying each element. The NumPy project maintains a detailed list of the equivalent functions between MATLAB and NumPy. Many functions operate identically ...
int: This refers to the integer data type in Python, which represents whole numbers (e.g., 5, -10, 0). Subscriptable: An object is "subscriptable" if you can access its internal items using square brackets []. Think of containers or sequences like lists (my_list[0]), tuples (my_...
