text: """[Lambda Expressions]
  Lambda expressions are simply another way to create functions       anonymous functions
  
  keyword \   parameter list optional
           \      \                the : is required, even for zero arguments
            \      \              /     / this expression is evaluated and returned when the lambda function is called. (think of it as "the body" of the function)
          lambda [parameter list]: expression
                  \
                  the expression returns a function object
                  that evaluates and returns the expression when it is called
  
  
          Examples
  
  from tkinter import Y
  from unittest import FunctionTestCase
  
  
  lambda x: x**2
  
  lambda x, y: x + y
  
  lambda : 'hello'
  
  lambda s: s[::-1].upper()
  
  
  type(lambda x: x**2)    -> function
  
  Note that these expressions are function objects, but are not "named"
          -> anonymous Functions
  
  lambdas, or anonymous functions, are NOT equivalent to closures
  
  
  
  
          Assigning a Lambda to a Variable name
  
  """
  
  my_func = lambda x: x**2
  
  type(my_func)  -> fuunction
  
  my_func(3)  -> 9
  
  my_func(4)  -> 16
  
  
  identical to: def
