🧪 Using Python with NumPy, Pandas, Matplotlib, and Seaborn for Data Analysis, Data Science & Pre-Machine Learning Analysis
  Before any machine learning model is built, the real work  lies in understanding, cleaning, transforming, and visualizing the data. This crucial phase is known as pre-machine learning analysis  or exploratory data analysis (EDA) .  In this post, we’ll cover how to use the most powerful Python libraries— NumPy, Pandas, Matplotlib, and Seaborn —for data analysis and pre-ML preparation.  Whether you're new to data science or sharpening your skills, this guide walks you through practical techniques to wrangle and understand your data before diving into algorithms.   🔧 The Essential Python Libraries for Data Analysis  Let’s briefly introduce the four core libraries:    NumPy  – The foundation for numerical computing in Python. It’s great for array operations, math, and basic statistics.    Pandas  – The go-to library for working with structured data (like CSV files, databases, spreadsheets).    Matplotlib  – A flexible plotting library to create static charts and graphs.    Seaborn  ...
