[Python] 파이썬으로 작성한 테트리스

이번 포스트에서는 파이썬으로 작성된 테트리스 소스를 공유해 드립니다. 이 소스는 제가 직접 작성한 코드는 아니고 누군가 작성해놓은 코드를(일종의 OpenSource겠죠?^^) 제 포스트에 공유하기로 했습니다. 

• 개발 환경

Windows 10 64bit, Python 3.5 기반에서 테스트를 하였습니다. 소스를 보시면 PyQT4를 사용을 하는데, Anaconda 2.4.0 (32bit)용을 사용하였습니다. Anaconda를 설치하시면 PyQT가 기본적으로 설치가 되어 있으므로 별도의 설치를 하지 않으셔도 됩니다.

• 실행화면 

 사용법은 이동은 화살표키, 블럭 빨리 떨어트리기는 스페이스바를 누르면 됩니다. 다시 시작은 테트리스를 다시 실행을 시켜야 됩니다. 추가적인 기능은 분석하시면서 코드를 추가해 보시기 바랍니다.
