Below will be the text of my unique solution. It has been beneficial to Many of us, so I did not need to delete it.
rapid and economical (it is possible to flatten the nested iterable partially, without the need of throwing away time around the remaining section you don't will need)
The colon, :, is what tells Python you are giving it a slice and not a regular index. This is exactly why the idiomatic way of constructing a shallow duplicate of lists in Python two is
But even that Sisyphean endeavor appears to be like effortless beside the struggle versus synthetic drugs. No sooner has a drug been blacklisted than chemists adjust their recipe and start churning out a subtly different a single.
Since the docs condition, list comprehensions are employed to produce a list utilizing a for-loop and has the final composition:

Synthetic objects or substances are usually established to fulfill human wants or fulfill certain applications, giving an alternative to Obviously occurring components or resources.
In my view, you'll understand and memorize better the Python string slicing notation when you evaluate it the following way (read on).
The third rule of slice assignment is, the assigned list (iterable) does not have to provide the very same length; the indexed slice is simply Find Out sliced out and changed en masse by whatever is currently being assigned:
