Pandas and NumPy:
Powerful Tools for
Data Analysis
Introduction to Pandas
Python library for data manipulation and analysis.
Data Structures
Series and DataFrames for
organizing data.
Data Cleaning
Handling missing values and
inconsistencies.
Data Exploration
Summarizing, grouping, and visualizing data.
Key Pandas Data Structures: Series and DataFrame
Building blocks for organizing and manipulating data.
Series
One-dimensional labeled array, similar to a column.
DataFrame
Two-dimensional labeled data structure, similar to a table.
Pandas Data Manipulation:
Indexing, Filtering, and
Transforming
Extracting, modifying, and reshaping data.
1 Indexing
Accessing specific rows,
columns, or cells.
2 Filtering
Selecting data based on
conditions.
3 Transforming
Applying functions and operations to data.
Pandas Data Analysis: Summarizing,
Grouping, and Visualizing
Extracting insights and presenting findings.
Summarizing
Calculating statistics like mean, median, and standard deviation.
Grouping
Combining data based on shared characteristics.
Visualizing
Creating charts and graphs for data exploration and communication.
Introduction to NumPy
Python library for numerical computing.
Arrays
Efficient multi-dimensional arrays for
numerical operations.
Mathematical Functions
A wide range of mathematical operations
for data analysis.
Linear Algebra
Functions for matrix operations and linear
algebra.
NumPy Arrays and
Mathematical Operations
Performing calculations and manipulations on numerical data.
Operations Description
Arithmetic Addition, subtraction,
multiplication, division, etc.
Trigonometry Sine, cosine, tangent, etc.
Linear Algebra Matrix multiplication, inversion,
etc.
Integrating Pandas and NumPy
for Efficient Data Processing
Leveraging the strengths of both libraries for powerful data analysis.
1 Load Data
