# About "Mini project - Weather DB with Python 3"

A simple personal project where I tie together some basic knowledge from Python 3 and SQLite databases, which I learned on my free time.

## What it is

A small command-line program that lets you search for a location, e.g. `Kvevlax, Finland`, and store its current weather info from OpenWeatherMap in an SQLite database. It also lets you view or delete the stored places and their weather data, afterwards.

## How to use

Download the `weatherdb.py` and `credentials.py` scripts to your machine.\

Run it using `python3 weatherdb.py` or `./weatherdb.py`. Make sure you fill the credentials file with your own OpenWeatherMap API key first.

If this is the first time you run `weatherdb.py`, enter the command `#clear` at the prompt to create the `.sqlite` database. Otherwise, you will get an error.

## Libraries and tools used

* Python 3 for the programming language, including the libraries `sqlite 3` for the database operations, and `urllib` and `json` for making REST API requests and parsing the responses.

* Visual Studio Code for writing the code

* [Postman](https://www.postman.com/) to get acquainted with OpenWeatherMap's REST API endpoint's responses

* [SQLite](https://www.sqlite.org/index.html) and the [DB Browser for SQLite](https://sqlitebrowser.org/) for the database

* [dbdiagram](https://dbdiagram.io/d) for designing the database diagram

### Database structure
