Data Analysis: NumPy

What are the key features and benefits of Jupyter Lab, and how does it differ from Jupyter Notebook?
- Work with multiple different files in one spot
- Integrated Jupyter Notebooks
What are the main functionalities provided by the NumPy library, and how can it be useful in Python programming, particularly for scientific computing and data manipulation tasks?

The NumPy library makes it easier to work with large datasets using arrays. It allows for quicker data manipulation and analysis operations on a dataset by providing a shorter and more readable syntax to reference the data using its shape.
Explain the basic structure and properties of NumPy arrays, and provide examples of how to create, manipulate, and perform operations on them.

NumPy allows you to convert standard multidimensional arrays into NumPy arrays which make it easier to manipulate the data and extract information from the data in the arrays.

To create a NumPy array, you declare the NumPy package with the array method and then pass in an array. Alternatively, you can use methods such as the zeros and random.rand methods to create an array filled with zeros or random numbers given the shape of the array as an argument. There are many other ways to create a NumPy array.
```
 import numpy as np

 my_array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

 numpy_array = np.array(my_array)
```
