How Python in Astronomy has Impacted by Professional Life

<p>In short, my participation in the Python in Astronomy in 2016 taught me what it takes to make software that is actual useful for others and revealed the incredible encouraging and supportive community of astronomy python coders. Just releasing software is not enough - it needs good documentation, automated testing, and encourage contributions from others. Interacting with the astronomy python community has shown me that it is now better for my career to make all my code public. As one illustration, I will use the dust_extinction package that I started after the 2016 meeting. This package provides dust extinction curves using the astropy affiliated template package and is based on the astropy modeling and units packages.
