Data-Science-Fundamentals-and-Tools

A complete guide to core Data Science concepts and tools using Python.

📁 Employee Management System (EMS)

📘 Explanation:

A beginner-friendly Python project designed to manage employee records using core programming concepts such as control structures, functions, and object-oriented programming. It supports essential operations like adding, viewing, and searching employees through a menu-driven interface. Employee data is stored in a dictionary with unique employee IDs, demonstrating basic CRUD operations and structured code organization.

📁 Advanced_Python_Tools_DataScience

🛠️ Explanation:

A hands-on assignment series to understand the core tools in Python for Data Science. This folder includes three subcategories: NumPy, Pandas, and Matplotlib — each focused on essential operations in data manipulation, analysis, and visualization.

🧮 NumPy_Assignment

Objective: Learn array creation, manipulation, and basic statistical operations using NumPy.
Key Tasks:

  • 1D and 2D array operations (sum, mean, std, transpose, slicing).
  • Element-wise and matrix operations (addition, multiplication, dot product).

🧾 Pandas_Assignment

Objective: Explore dataframes, group operations, filtering, and saving data using Pandas.
Key Tasks:

  • Creating DataFrames from dictionaries.
  • Filtering by conditions, calculating aggregates.
  • Adding columns, grouping, sorting, and exporting to CSV.

📊 Matplotlib_Assignment

Objective: Practice data visualization through line plots, bar charts, pie charts, and histograms.
Key Tasks:

  • Line plot customization.
  • Bar chart for student scores.
  • Pie chart with region-wise revenue.
  • Histogram for random data distribution.
