A tool for checking the average WG ratings of your teams and enemies teams in World of Tanks

Go to the Wargaming Developer room, sign in, and create a new server application. Provide your external IP address i.e. what what's my ip tells you, not your machine's LAN address.
This lets you make non-rate limited API queries

usage: replay_analyser.py [-h] [-w] [-k KEY] dir [dir ...]

A tool to analyse replays.

positional arguments:
  dir                path to directory(s) containing replays

optional arguments:
  -h, --help         show this help message and exit
  -k KEY, --key KEY  application id (key) from
                     https://developers.wargaming.net/applications/ (optional)

The program creates a cache.csv file so, if you need to stop it, WG results will not be fetched again. You can re-run or continue from where you left off. 

Go to releases and download the latest version.
The executable can be run from the command line (cmd or powershell).

https://www.python.org/ftp/python/3.6.4/python-3.6.4-amd64-webinstall.exe
When you install, ensure you select the "add to path" option (will be something like that). It should be on the first page of the installer, otherwise you'll have to set it up manually, which is a pain.

Open a new Cmd or PowerShell window. Assuming path is correctly set up, just run:

pip install requests
pip install matplotlib

Either download the latest .zip and unpack to a directory of your choice, or clone the repo

In a Cmd or Powershell terminal, navigate to the directory where the unpacked code is
cd C:\full\path\to\containing\directory
Then run the code.
