This example demonstrates how to serialize a pandas DataFrame into JSON using Flask-RESTful’s `marshal_with` decorator. The code defines a `todo_fields` structure that maps DataFrame columns to output keys, including an attribute alias for `col1`. A `JsonContent` resource returns the DataFrame converted to records, and the decorator applies the field mapping to shape the response. The API runs on localhost:8080, showing how `fields.String` and `marshal_with` transform raw pandas data into a clean, structured API payload.

refactor of a flask python app for displaying nested text status entries

This example presents a Flask web application that displays nested text status entries as threaded HTML lists. It shows how a tree of toots, loaded from a JSON file, is rendered for either all authors or filtered by a specific author. The code uses the Flask framework to define routes and render templates, while custom Python classes, `Toot` and `TootsManager`, manage the hierarchy and generate the nested `<ul>` and `<li>` markup. An `AuthorsManager` handles author lookups, linking each toot to its poster. The visualization relies on the application’s server-side rendering, not on JavaScript libraries.

This example presents a collection of Python code snippets for data manipulation with the pandas library, focusing on common DataFrame operations. It demonstrates techniques for filtering rows based on column values, handling missing data, renaming columns, and performing data type conversions. The snippets also cover more advanced operations like pivot tables, merging delimited values, and using `pd.melt` for reshaping data. The code includes functions like `df.column_name.unique()`, `pd.pivot_table`, and `df.assign` to illustrate practical workflows for cleaning and transforming tabular data.

Transformation of DataFrame

This example demonstrates a straightforward transformation of a pandas DataFrame into a two-column structure, converting the original column headers and first-row values into paired “node” and “value” entries. The code builds a list of tuples via `zip(df.columns.tolist(), df.iloc[0,:].values.tolist())`, then wraps it in a new `pd.DataFrame` with the specified column names. No visualization library or rendering occurs; the output is purely tabular, showing how data can be reshaped for downstream analysis or charting.

This example builds a profile-scraping pipeline for social media data, turning raw CSV input into a structured DataFrame with fields for user names, follower counts, post dates, likes, comments, captions, and industry tags. The code reads `raw_data.csv` via `pandas.read_csv` and then initializes an empty DataFrame with predefined column names, preparing it for subsequent population. The visualization focuses on the data-preparation stage rather than graphical output, demonstrating how pandas handles tabular ingestion and schema definition. No rendering library like d3 or Three.js appears here; instead, the emphasis is on clean data structuring for later analysis or charting.

This example highlights differences between two pandas DataFrames by key. It displays the two records side-by-side, transposing them into a single table where each column represents a field. Any column containing differing values between the two rows is visually marked with a yellow background. The implementation uses the pandas `DataFrame.style.apply` method to apply a custom `highlight_diff` function that checks for uniqueness across the row pairs, returning conditional formatting styles for the table.

Make it pretty - Playing around with CSS, SVG, Animated CSS in Jupyter Notebook

This example demonstrates how to style and animate pandas DataFrames within a Jupyter Notebook using custom CSS and SVG. It applies a fantasy font, colored table headers and cells, and integrates the animate.css library to add animated effects like bouncing. The code injects CSS rules directly into the notebook’s HTML output, transforming standard table rendering into a more visually engaging presentation.

A README file for the lecture on 2018-10-20

This example is a lecture README for a 2018 Pandas course, showing how a single gist organizes teaching materials, dependencies, documents, and a post-class survey. It demonstrates the use of Python libraries—Jupyter Lab, NumPy, Pandas, Matplotlib, Scikit-learn, and Graphviz—for data processing, visualization, and a decision-tree machine learning exercise. The text details installation via pip, conda, or pipenv, and links to tutorial notebooks, slides, and cheatsheets. The rendering approach is plain Markdown, with no interactive or programmatic visualization code present.

This example displays a pandas DataFrame table listing 14 unique superpowers alongside their corresponding heroes, such as Kool-Aid Man’s Thirstokinesis and Dr. Manhattan’s Molecular Dissipation. The code constructs the table from a Python dictionary using `pd.DataFrame.from_dict`, rendering the data as an HTML table with styled headers and row indices. The output is a static, text-based visualization of the one-to-one mapping between each distinct ability and its associated character, with no charts or graphical elements involved.
