Test the real thingsToday,because of multicultural issues,many peoples are entering Europe and US who are newbies in programming.This is a snare to quality demands in Software Engineering. I am graduated german software engineer offering systematic,high level software engineering at reasonable rates.Contact me at +4915172972526 or [email protected] to receive high quality software Below you find a freeware Python program for calculation of cryptocurrency wallets' total value.Have a look at it to get convinced of my software development capabilities. #
