This article mainly introduces the code sharing of an Automatic Beverage Sales program implemented by Python, that is, the internal program judgment code of a coin-operated automatic beverage sales machine implemented by python, I have been learning Python for nearly one hundred hours. On CSDN, I saw someone asking for help using Python to write a program for auto-selling drinks, I want to try to write a practical vending program. Of course, it is just to implement basic functions. You are welcome to give pointers and learn from new users.

Running Environment: Python 2.7
