Data Science
Data is rarely clean and never in the required structure!!
Whether you are starting with data science or are an experienced professional — You won’t deny the above statement!
In a data analyst’s career extracting actionable insights from data is a critical skill. And often you face challenges with messy, inconsistent, and unstructured data.
As per my experience, traditional data cleaning methods are tedious and error-prone, especially when dealing with massive amounts of data such as in a data warehouse. You spend a couple of hours just to bring this data to its workable state.
But, what if I tell you a single module in Python can make your life easy?
Yes, such features exist.
Python’s re
module is all you need.
The re module in Python is a built-in library that supports Regular Expressions or regex. A regular expression is nothing but a pattern which is used to match character combinations in text or string. I found it as a really powerful tool for text processing.
