Description

Program shows weather and next day forcast for given cites

It's also demonstrates how long it takes time for different methods of request

• reatriev_weather button - do common synchronous requests to the weather server

• retrieve_weather_async button - fulfill asynchronous requests to the server (which do not block UI and executes much faster)

• retrieve_weather_thread button - make the requests in their own threaded, as pysimplegui docs proposes (these requests are fast and do not block UI either like async requests, but at demonstration You can see a delay caused probably by threading creation (or even more probably becayse this method need to be used inside common synchronous loop over asynchronous like here))

• Clock - demonsrates either or not UI to be blocked by defferent methods

Install

Linux To install the app run one of these blocks in terminal:

• if poetry:

git clone https://github.com/sunCelery/async_pysimplegui && \
cd async_pysimplegui && \
poetry install

• elif pip:

git clone https://github.com/sunCelery/async_pysimplegui && \
cd async_pysimplegui && \
python -m venv .venv && source .venv/bin/activate && \
python -m pip install --upgrade pip && pip install .

Windows: after you clone repository go to the folder and run command in Your terminal:

py -m venv venv && venv\Scripts\activate ^
py -m pip install --upgrade pip && pip install .

probably instead 'py' You should type 'python'

Usage

You need 'APPID.txt' file with Your API-KEY in there for program to work

To launch the app run one of these blocks in terminal

Linux

• if poetry:

poetry run python main.py

• else:

python main.py

Windows

python main.py

To Do

• [done] make aiohttp request which not block UI
• [done] clean code style, delete global variables
• [done] implement variant of function which uses thread (window.perform_long_operation) method
• [done] lead to OOP
