 * # Python 3: Fibonacci series up to n
   >>> def fib(n):
   >>>     a, b = 0, 1
   >>>     while a < n:
   >>>         print(a, end=' ')
   >>>         a, b = b, a+b
   >>>     print()

   FUNCTIONS DEFINED
   
   The core of extensible programming is defining functions. Python allows
   mandatory and optional arguments, keyword arguments, and even arbitrary
   argument lists. More about defining functions in Python 3

 * # Python 3: List comprehensions
   >>> fruits = ['Banana', 'Apple', 'Lime']
   >>> loud_fruits = [fruit.upper() for fruit in fruits]
   >>> print(loud_fruits)
   ['BANANA', 'APPLE', 'LIME']
   
   # List and the enumerate function
   >>> list(enumerate(fruits))
   [(0, 'Banana'), (1, 'Apple'), (2, 'Lime')]
   
   
   COMPOUND DATA TYPES
   
   Lists (known as arrays in other languages) are one of the compound data types
   that Python understands. Lists can be indexed, sliced and manipulated with
   other built-in functions. More about lists in Python 3

 * # Python 3: Simple arithmetic
   >>> 1 / 2
   0.5
   >>> 2 ** 3
   8
   >>> 17 / 3  # classic division returns a float
   5.666666666666667
   >>> 17 // 3  # floor division
   5
   
   
   INTUITIVE INTERPRETATION
   
   Calculations are simple with Python, and expression syntax is
   straightforward: the operators +, -, * and / work as expected; parentheses ()
   can be used for grouping. More about simple math functions in Python 3.

 * # For loop on a list
   >>> numbers = [2, 4, 6, 8]
   >>> product = 1
   >>> for number in numbers:
   ...    product = product * number
   ... 
   >>> print('The product is:', product)
   The product is: 384
   
   
   ALL THE FLOW YOU’D EXPECT
   
   Python knows the usual control flow statements that other languages speak —
   if, for, while and range — with some of its own twists, of course. More
   control flow tools in Python 3

 * # Simple output (with Unicode)
   >>> print("Hello, I'm Python!")
   Hello, I'm Python!
   # Input, assignment
   >>> name = input('What is your name?\n')
   What is your name?
   Python
   >>> print(f'Hi, {name}.')
   Hi, Python.
