This workshop will cover the use of Python tools for astronomical data analysis and visualization, with the focus primarily on tools in the Astropy library and its affiliated packages. The goal is to introduce participants to the variety of tools which are available inside the Astropy library and to provide ample hands-on time during which participants will explore the science analysis capabilities which the greater Python environment and community provide. The format will be very interactive and include short presentations followed by instructor-guided tutorials where participants will use the tools be able to ask questions in the company of expert users and developers. Topics will include units, quantities, and constants; FITS, ASCII, and Astropy tables; point-source photometry; and data exploration and visualization.
