Python online running code assistant

The Python code running assistant allows you to input Python code online, and then execute the code using a Python script running on the local machine. the Python code running assistant allows you to input Python code online, then run the code through a Python script running on the local machine. The principle is as follows:

Enter code on the webpage:

Click the Run button to send the code to the Python code running assistant running on the local machine;

The Python code execution assistant saves the code as a temporary file and then calls the Python interpreter to execute the code;

The code execution result is displayed on the webpage:
