def choreography():

def myFunction():
 array = [1,2,3,4]

The error was:(I used both arr and array)
Name not found globally.
A local or global name could not be found. You need to define the function or variable before you try to use it in any way.

  arr = myFunction()
  doSomething(arr)

def doSomething(arr):
  commands to manipulate the turtles in arr
