Introduction to Python Numpy

Numpy is Python open source packages which make the numerical computing possible in Python using N dimensional array. This forms the foundation of other data munging and manipulation packages such as Pandas.

Let’s look at why Numpy is needed. Assume that we want to add members of two lists as shown in the below example.

As you can see from the above example, numerical computing is possible in Python largely due to Numpy.

Let’s dig deeper into other aspects on Numpy.

Install and check Python Packages

Here are some examples on how you can check that necessary packages are installed in the python environment and check their version before moving forward. These are some of the must have packages. If any of the packages are not installed, you can do the anaconda install using conda prompt.  Further directions are shown in the link 

You can search for any package in anaconda environment by using the following code-

anaconda search -t conda seaborn
