Python's built-in functions list includes 71 functions now! Which built-in functions are worth knowing about? And which functions should you learn later?| www.pythonmorsels.com
Python's variables are not buckets that contain objects; they're pointers. Assignment statements don't copy: they point a variable to a value (and multiple variables can "point" to the same value).| www.pythonmorsels.com
List comprehensions make lists; generator expressions make generators. Generators are lazy single-use iterables which generate values as you loop over them.| www.pythonmorsels.com
An iterable is anything you're able to iterate over (iter-able). Iterables can be looped over and anything you can loop over is an iterable. Not every iterable is indexable or has a length.| www.pythonmorsels.com
