Numpy is one of the best libraries to deal with scientific calculation. What I feel is the best about it is that they provide multiple functions and we can say it's powerful for handling big calculations and also makes things easy for programmers. For example, I fetch some data from websites like Quandl or NSE in CSV format, read that CSV file, and load that data into a single list. So, what if I want to change the dimension of that list? Numpy provides that type of function; we can change the dimension using a single function. Review collected by and hosted on G2.com.
The only con is that if you don't know about Numpy functions, you might face some issues while programming. Apart from that, if you are using a normal IDE or Python CLI, you have to download the Numpy library because these libraries are not provided by Python. You have to install it yourself.
