Data Science:- 2. Data Preprocessing using Scikit Learn

Data preprocessing is an important step in the data mining process. The phrase “garbage in, garbage out” is particularly applicable to data mining and machine learning projects. Data-gathering methods are often loosely controlled, resulting in out-of-range values, impossible data combinations, and missing values, etc. There are a lot of preprocessing methods but we will mainly focus on the
