Video Code Review with Veky: contextlib and ast

In this video veky go through a lot of topics

• What is contextlib and how does it work with veky’s family tree solution.
• Try.. except: pass is the most dangerous idiom in Python and why.
• Zen of Python (import this)
• why “suppress" but not “ignore”
• why don’t we have warning for using Try.. except: pass ?
• Hierarchy of Exception Classes
• How Exceptions works in Python 1
• sys.last_type sys.last_value
• veky’s "The Good Solution" of "The Good Radix” mission
• special place of “not” in the grammar
• how suppress works as break and continue
• min and max solution (not veky’s)
• what is special in min and max in Python and why Guido was very unhappy about it
• deduplicating your code
• using default arguments for passing values into nested function
• when you understand that some things are data and some things are code it becomes much easier to understand the rest.
• "What is the name of this cat"
• Inserting into global and local namespaces
• functools.wraps
• ast.literal_eval and eval function
• a bonus: crazy funny adding solution (PyRPy)
