Using multiple loops to program multiple repetitions


Series 4 : Writing methods
Splitting problems into parts
  Series 5 : Variables.
Using variables; telling the difference between local and instance variables
  Series 6 : if-else-structure
Program branching because of specific conditions; random numbers
  Series 7 : Using multiple Turtles
