We begin by unpacking the cheat sheets for core Python libraries: NumPy, which lays the groundwork for numerical operations; Pandas, the go-to for data manipulation; and Matplotlib, the bedrock of data plotting in Python. Seamlessly, we transition into libraries like Seaborn, which builds on Matplotlib to provide a higher-level interface for statistical visualizations, and SciPy, which extends the capabilities into scientific computing.
