@nixCraft Indentation is frustrating, ambiguous unlike braces. Dynamic typing is dangerous and makes using somebody else's API needlessly complicated (what is this method expecting?). Haven't found an IDE anywhere near the equal of Eclipse. Biggest problem, it is very very slow. I find Java runs 10x faster. And versioning/environment/dependencies nightmares. Unfortunately, lots of scientific libraries are written in Python, so I'm stuck sometimes using it unless I can find an alternative.
