Python script to redeem bulk steam keys

RedeemKeys.py

'''

	Python3 Bulk Steam key importer

	Requires the pip library 'steam'
	Run `pip install steam` if you're unsure

	Code expects a text file with keys line seperated. For example:
	
	XXXXX-YYYYY-ZZZZZ
	AAAAA-BBBBB-CCCCC

	would be a valid file.

	I'm not affiliated with Valve and use of this code is at your own risk.
