How to use the demo function in Python?

In Python, the demo function refers to a function used to demonstrate or showcase a certain feature. The steps for using the demo function are as follows:

1. Import the module where the demo function is located. If the demo function is within a module called module, you can use either import module or from module import demo to import it.
2. Call the demo function. If the demo function has parameters, you can pass the parameters in the order defined in the function. For example, if the demo function has two parameters param1 and param2, you can use demo(param1, param2) to call it.
3. Check the output of the demo function. The demo function may return a result or simply output some information. Depending on the situation, you can use the print statement to print the output or use other methods to view the output.

Here is a simple example demonstrating how to use a function called demo:

# 导入demo函数所在的模块
import module

# 调用demo函数
result = module.demo()

# 打印输出结果
print(result)

Please note that this is just an example, specific usage may vary depending on the module and function definitions of the demo function. Adjustments should be made according to the actual circumstances during use.
