PidyTuesday

PidyTuesday is a Python library that ports the functionality of the TidyTuesday CRAN package to Python. It provides a suite of command-line tools for accessing and downloading TidyTuesday datasets hosted on GitHub.

Features

• Get the most recent Tuesday date: Useful for aligning with TidyTuesday releases.
• List available datasets: Discover available TidyTuesday datasets across years.
• Download datasets: Retrieve individual files or complete datasets.
• Display dataset README: Open the dataset's README in your web browser.
• Check GitHub API rate limits: Monitor your GitHub API usage.

Installation

Using uv (recommended)

We make extensive use of uv and uv tools to enable command-line scripts without too much managing of virtual environments.

1. Install uv.

2. Install PyDyTuesday to your commandline by using uv tool install

   uv tool install pydytuesday
   
   pydytuesday last-tuesday
   

Alternatively, you can use uv tool or uvx to avoid adding the command to your path.

uv tool pydytuesday last-tuesday

or using uvx:

uvx pydytuesday last-tuesday

Using pip

Alternatively, you can install the library directly into your environment using pip.

pip install pydytuesday

pydytuesday last-tuesday

Usage

Once you have installed the library using uv, you should be able to run your commands from anywhere on your system.

• Last Tuesday

  • Description: Prints the most recent Tuesday date relative to today's date or an optionally provided date.
  • Usage:

    pydytuesday last-tuesday
    pydytuesday last-tuesday 2025-03-10
    

    (The second example passes a specific date argument in YYYY-MM-DD format.)

• TidyTuesday Available

  • Description: Lists all available TidyTuesday datasets.
  • Usage:

    pydytuesday tt-available
    

• TidyTuesday Datasets

  • Description: Lists datasets for a specific year.
  • Usage:

    pydytuesday tt-datasets 2025
    

    (Example passes the year as an argument.)

• Download Specific File

  • Description: Downloads a specified file from a TidyTuesday dataset by date.
  • Usage:

    pydytuesday tt-download-file 2025-03-10 data.csv
    

    (The example downloads the file 'data.csv' from the dataset for March 10, 2025.)

• Download Dataset Files

  • Description: Downloads all or selected files from a TidyTuesday dataset by date.
  • Usage:

    pydytuesday tt-download 2025-03-10
    pydytuesday tt-download 2025-03-10 data.csv summary.json
    

    (The first example downloads all files from the dataset for March 10, 2025. The second example downloads only the specified files.)

• Display Dataset README

  • Description: Opens the README for a TidyTuesday dataset in your default web browser.
  • Usage:

    pydytuesday readme 2025-03-10
    

    (The example opens the README for the dataset from March 10, 2025.)

• Check GitHub Rate Limit

  • Description: Checks the remaining GitHub API rate limit.
  • Usage:

    pydytuesday rate-limit-check
    

Example Workflows

Command-line Workflow

Here's a complete example of how to discover, download, and explore TidyTuesday data using the command-line interface:

# 1. Find the most recent Tuesday date
pydytuesday last-tuesday
# Output: 2025-03-11

# 2. List available datasets for a specific year
pydytuesday tt-datasets 2025
# Output: Lists all datasets for 2025 with dates and titles

# 3. Download a specific file from a dataset by date
pydytuesday tt-download-file 2025-03-11 example.csv
# Output: Successfully saved example.csv to /path/to/example.csv

# 4. After downloading, you can read the CSV file using pandas in Python:
import pandas as pd

# Read the downloaded CSV file
df = pd.read_csv("example.csv")

# Display the first few rows
print(df.head())

# Get basic information about the dataset
print(df.info())

# Generate summary statistics
print(df.describe())

# Perform data analysis and visualization
import matplotlib.pyplot as plt
df.plot(kind='bar', x='category', y='value')
plt.title('TidyTuesday Data Analysis')
plt.show()

This workflow demonstrates how to use the command-line tools to discover and download data, and then use pandas to analyze the downloaded data.

Python Library Workflow

You can also use PyDyTuesday as a Python library directly in your code:

# Option 1: Use PyDyTuesday to download files
import PyDyTuesday

# Download all files from a specific week
PyDyTuesday.get_date('2025-03-18')
# This will save all files from the 2025-03-18 dataset to your current directory

# Download files from a specific week by year and week number
PyDyTuesday.get_week(2025, 3)
# This will download all files from the 3rd week of 2025

# Option 2: Read directly from GitHub
import pandas as pd

# Read a CSV file directly from GitHub without downloading
palmtrees = pd.read_csv('https://raw.githubusercontent.com/rfordatascience/tidytuesday/main/data/2025/2025-03-18/palmtrees.csv')

# Analyze the data
print(palmtrees.head())

This workflow demonstrates how to use PyDyTuesday as a Python library to download data or read it directly from GitHub.
