Variables allow us to store things in memory for as long as the Python program runs. Like a restaurant reservation under your name, a variable is a named reservation of a small part of your computer's memory. We assign a...

We can create ndarrays using the np.array function. We need to use nested lists to introduce the extra dimensions. As you can see when running this example, the output (when using print) can become a bit hard to read. This...

When creating NumPy arrays, the copy argument controls whether a copy of the input object is made or not. When copy is True, any changes in the resulting array will not change the input object. However, if it is False,...

Here's how to read a CSV file using Python. The csv.reader returns Python lists for each row. We print them here, but you can do anything you want with the parsed data....
