Data Science is a very important job in today's age of data being the aspect that plays a vital role in most of the field whether it may be the medical field, business, agriculture, engineering, sports and the list go on and on. Python is one of the programming language, which is used for data science and machine learning. It consists of many libraries and a very good community built within the past couple of decades. And it also has the upper hand among other languages as this same language can be used to build the system. While I talk about libraries in Python for Data Science(DS), the first library that come into thought is "NumPy", NumPy (abbreviation for Numerical Python) is the library built with the purpose of scientific calculation in numerical data. It is best for storing the numerical values in an array as a NumPy array that may be single or multi-dimensional (also called Tensors). "Okay, then why not List?" T...
