Which IDE for scientific computing and plotting in Python?

I am currently using R for all my scientific computing and plotting, but I would like to explore Python. I have been using RStudio as an IDE for R, which as an IDE fulfills 100% of my need for scientific computing, number crunching, data analysis and visualizations. Is there something similar for Python? Basically syntax highlighting, code completion, smart indentation, code execution directly from the source editor, plotting within the IDE and version control (git).
