Python Brasil is the biggest Python conference in the country, and one of the most fun and informative times I've had in my life. the Python community is amazing, always helpful, sincere, and friendly. it happens every year, and I've been to a lot of them since I started programming in 2010.
if you have any interest in the language, and have the time and resources to go, I totally recommend it. it's always a fun time, and we would most likely meet there :]
