No Python at 'E:\Python\python.exe 什么意思

The message "No Python at 'E:\Python\python.exe" means that the system was unable to find a Python installation at the specified location, which is "E:\Python\python.exe".

Python is a programming language, and to execute Python code, you need a Python interpreter, which is usually installed on your system. The interpreter is the program that reads your Python code and runs it. The interpreter is typically installed in a directory on your computer, and the location of this directory is added to your system's PATH environment variable, which allows you to run Python from any directory on your computer.

The message you received indicates that the system could not find a Python interpreter at the specified location. This could be because the interpreter is not installed in that directory, or the PATH environment variable is not configured correctly. To fix this issue, you should check that Python is installed on your system, and if it is, ensure that the PATH environment variable includes the directory where the Python interpreter is installed.
