To include Python in the list of environment variables for Tomcat 9, follow these steps:

1. Locate the catalina.bat or catalina.sh file in the bin folder of the Tomcat installation directory.

2. Open this file in a text editor and locate the section where environment variables are set. In catalina.bat, this section should be labeled "Set environment variables." In catalina.sh, it should be labeled "Environment setup."

3. Add the following line to set the path to the Python executable:

   set PYTHON_HOME=<path to="" python="" installation="" directory="">

   For example, if Python is installed in C:\Python37, the line should be:

   set PYTHON_HOME=C:\Python37

4. Add the following line to append the Python path to the system path:

   set PATH=%PATH%;%PYTHON_HOME%

5. Save the file and restart Tomcat for the changes to take effect.

With these steps, Python should now be included in the list of environment variables for Tomcat 9.
