Python implements 2048 games and python2048 games

Python 2048. Modified the code of a user to solve two bugs in the original user version:

1. The original game is eliminated only once each time, rather than recursively. For example, if [2, 2, 2] is left, it should be [4, 4, 0, 0] instead of [8, 0, 0, 0].
2. There is a bug in the detection of the end of the game, which has been corrected.
