Python Run code Helper online

The Python Code run helper allows you to enter Python code online and execute the code from a Python script run natively. The principle is as follows:

Enter the code on the Web page:

Click the Run button and the code is sent to the running assistant of the Python code that is running on the computer;

The Python Code run helper Saves the code as a temporary file and then invokes the Python interpreter to execute the code;

The Web page displays code execution results:

Run

Run the command in the directory where the learning.py is stored:
Copy the Code code as follows:

C:\users\michael\downloads> python learning.py

If you see ready for Python code on port 39093 ... indicates a successful run, do not close the command-line window, and minimize it to run in the background:
