3.6 What does “Pythonic” mean?

You’ve now seen enough of Python to see that it is a powerful and elegant programming language. You are coding in a Pythonic way when you take advantage of that elegance and further create something that beautifully and succinctly accomplishes your task. Examples of being Pythonic include:

• You use for in a loop such as for item in my_list:, instead of defining and using an index to access list members.
• You interchange the values of two variables using simultaneous assignment.
• You make a new list in reverse order from an existing list using slicing:
  my_list[::-1].
• You code a comprehension to build a new list instead of using append:

  [x**2 for x in range(13) if x % 3 == 0]
  

  [0, 9, 36, 81, 144]
  

You’ll see other examples as we move through this introduction to Python.
