Stop using print statements forever! You'll learn how to use these tools: PUDB - an interactive, ncurses debugger Charles - a web debugging proxy cProfile - python's built-in profiling library RunSnakeRun and SnakeViz - Tool for visualizing profile output I'll also talk about the process of debugging and profiling, common error patterns and how to use your time most efficiently.
