Lessons Learned

• 01.12.
  • First time using doctests.
• 02.12.
  • Remember: itertools.product is the Replacement for n for loops.
  • Remember: l=l2.copy() to make a shallow copy
• 06.12.
  • Remember: x = lambda input : output
  • For larger tests doctest is not the right choice. Need to restructure for the next intcomputer
  • For the next graph puzzle I'll try NetworkX instead of just using a dict.
  • Remember: python3: d.items(), python2: d.iteritems()
• 07.12.
  • itertools.permutations gives all possible permutations
  • generators for input where not the best choice
• 08.12.
  • Remember: numpy shape is called with array as argument and reshape is called as function from array
