The first decision you need to make is which version to download. The Python 2.7 or the Python 3.x. If you are a beginner and you are just starting to learn Python, then you should download 3.x. On the other hand, if you need to work on some legacy Python based application which depends on older libraries that cannot be ported, then you are better off with 2.7. But moving forward, there will not be any new releases on 2.7 Python. Eventually all have to migrate to 3.x version which is improved and most of the libraries are porting to the newer version. So Just go with version 3.x. Download the right release based on whether you are using Windows, Linux or Mac. Just download and install it in the default location.

Python String objects (byte strings, as well as text, AKA Unicode, ones) are immutable: attempting to rebind or delete an item or slice of a string will raise an exception. The items of a string object (corresponding to each of the characters in the string) are themselves strings of the same kind, each of length 1.

A Python list is a mutable ordered sequence of items. The items of a list are arbitrary objects and may be of different types. To denote a list, use a series of expressions (the items of the list) separated by commas (,), within square brackets ([]); if every item is a literal, the whole assembly is a list literal. You may optionally place a redundant comma after the last item. To denote an empty list, use an empty pair of brackets

Python while statement repeats execution of a statement or block of statements, until the loop condition is true. Once the loop body finishes executing, Python evaluates the loop condition again from the top to check whether another iteration should execute. This process continues until the loop condition is false, at which point the while statement ends.
