How to open CSV files in Python store and retrieve large data sets

A CSV file is a “comma-separated values” file. In plain English, this is a text file that contains an unusually large value of data. More often than not, this is used in order to create databases of information, where each unit of data is separated by a comma. Hence the name!

Being worldly-wise to manipulate, load, and store large amounts of data is a hugely salubrious skill when programming. This is particularly true in Python, seeing as Python is such a popular option for machine learning and data science.
