Created page with "This is a [https://www.python.org/downloads/ Python] script to generate the Drop rates tables. Copy the code in the box below into a text file named '''<nowiki>wikiDropRat..."

New page

This is a [https://www.python.org/downloads/ Python] script to generate the [[Drop rates]] tables. Copy the code in the box below into a text file named '''<nowiki>wikiDropRates.py</nowiki>''' (or whatever you want) inside the '''<nowiki>Wildermyth</nowiki>''' directory. Then run it by calling '''<nowiki>python wikiDropRates.py</nowiki>''' from the command line.<ref>More precisely, you can put the script anywhere, but you need to call it from the '''<nowiki>Wildermyth</nowiki>''' directory.</ref> It will create a text file named '''<nowiki>wikiDropRates.txt</nowiki>''' with the appropriate wiki-formatted content.
