pywarsaw

An unofficial asynchronous API wrapper for Warsaw Open Data.

Created mainly for learning purposes.

Package is still in progress, check the work status in the currently covered section.

Features

• Asynchronous: designed to work with asyncio
• Extensive: cover as many endpoints as possible
• Approachable: all polish fields translated to english
• Responsible: minimize the load on the API server
  • implemented caching
• Simple: easy to use and customize:
  • object-oriented design
  • use of data transfer objects
  • type hinting
  • convert adequate fields from strings to the more suitable types
• Lightweight: minimal usage of the third-party packages

Installation

pip install pywarsaw

Getting started

The package goal is to be straightforward to use. For example, you can obtain a list of objects with information about current air quality in Warsaw, with caching enabled like this:

import asyncio
import pywarsaw

async def main():
    client = pywarsaw.Mermaid(api_key="YOUR_API_KEY")
    await client.cache_enable()

    result = await client.get_air_quality()
    
    await client.close()

asyncio.run(main())

Or with the context manager:

async with pywarsaw.Mermaid(api_key="YOUR_API_KEY") as client:
    await client.cache_enable()
    
    result = await client.get_air_quality()

Caching can be disabled with:

await client.cache_disable()

Every object from the obtained list an be converted to the simpler structures:

# convert object to the dictionary
result_dict = result[0].to_dict()

# convert object to the tuple
result_tuple = result[0].to_tuple()

# convert object to the flat dict - useful for creating Pandas dataframes
result_flat = result[0].to_flat_dict()

# convert object to the json string
result_json = result[0].to_json()
