Khóa học phân tích dữ liệu Python chuyên sâu: NumPy & Pandas

This is a hands-on, project-based course designed to help you master two of the most popular Python packages for data analysis and business intelligence: NumPy and Pandas.

We'll start with a NumPy primer to introduce arrays and array properties, practice common operations like indexing, slicing, filtering and sorting, and explore important concepts like vectorization and broadcasting.

From there we'll dive into Pandas, and focus on the essential tools and methods to explore, analyze, aggregate and transform series and dataframes. You'll practice plotting dataframes with charts and graphs, manipulating time-series data, importing and exporting various file types, and combining dataframes using common join methods.

Throughout the course you'll play the role of Data Analyst for Maven Mega Mart, a large, multinational corporation that operates a chain of retail and grocery stores. Using the Python skills you learn throughout the course, you'll work with members of the Maven Mega Mart team to analyze products, pricing, transactions, and more.

COURSE OUTLINE:

• Intro to NumPy & Pandas

  • Introduce NumPy and Pandas, two critical Python libraries that help structure data in arrays & DataFrames and contain built-in functions for data analysis

  
  

• Pandas Series

  • Introduce Pandas Series, the Python equivalent of a column of data, and cover their basic properties, creation, manipulation, and useful functions for analysis

  
  

• Intro to DataFrames

  • Work with Pandas DataFrames, the Python equivalent of an Excel or SQL table, and use them to store, manipulate, and analyze data efficiently

  
  

• Manipulating Python DataFrames

  • Aggregate & reshape data in DataFrames by grouping columns, performing aggregation calculations, and pivoting & unpivoting data

  
  

• Basic Python Data Visualization

  • Learn the basics of data visualization in Pandas, and use the plot method to create & customize line charts, bar charts, scatterplots, and histograms

  
  

• MID-COURSE PROJECT

  • Put your skills to the test with a brand new dataset, and use your Python skills to analyze and evaluate a new retailer as a potential acquisition target for Maven MegaMart

  
  

• Analyzing Dates & Times

  • Learn how to work with the datetime data type in Pandas to extract date components, group by dates, and perform time intelligence calculations like moving averages

  
  

• Importing & Exporting Data

  • Read in data from flat files and apply processing steps during import, create DataFrames by querying SQL tables, and write data back out to its source

  
  

• Joining Python DataFrames

  • Combine multiple DataFrames by joining data from related fields to add new columns, and appending data with the same fields to add new rows

  
  

• FINAL COURSE PROJECT

  • Put the finishing touches on your project by joining a new table, performing time series analysis, optimizing your workflow, and writing out your results
