Tetris In Python Code
The Tetris In Python Code is a GUI based title matching puzzle game which is very easy to understand and use. Talking about the gameplay it’s all same as the real one. The user has to manage the random sequence of Tetriminos. This Tetris Game In Python project, I will teach you on How To Make A Tetris Game In Python.
A Tetris Game Python player has steps to be follow of playing the game, first the player has to move each one sideways and rotate quarter-turns to form a solid horizontal line without leaving gaps. It disappears whenever such lines are formed. The user can only enter to next level if they cross the specific number by the game rules. As the game progresses, the Tetriminos falls faster and faster. As a result, the game ends when the stack of Tetriminos reaches to the top of the field and no new Tetriminos are able to enter.
Watch the video here to see the full running tetris game in python with source code.
Anyway if you want level up your knowledge in programming especially games in python, try this new article I’ve made for you Code For Game in Python: Python Game Projects With Source Code
This Tetris Game In Python also includes a downloadable Tetris Game Source Code In Python, just find the downloadable source code below and click to start downloading.
To start Create Tetris In Python,makes sure that you have PyCharm IDE installed in you computer.
By the way if you are new to python programming and you don’t know what would be the the Python IDE to use, I have here a list of Best Python IDE for Windows, Linux, Mac OS that will suit for you. I also have here How to Download and Install Latest Version of Python on Windows.
Steps on how to create Tetris In Python Code
Tetris In Python Code
- Step 1: Create a project name.
First open Pycharm IDE and then create a “project name” after creating a project name click the “create” button.
- Step 2: Create a python file.
Second after creating a project name, “right click” your project name and then click “new” after that click the “python file“.
- Step 3: Name your python file.
Third after creating a python file, Name your python file after that click “enter“.
- Step 4: The Actual Code.
You are free to copy the code given below and download the full source code below.
