     Py_Initialize();
     PyRun_SimpleString("print("hello")");
     Py_Finalize();
     return 0;

The error message

Error E2209 C:\Borland\bcc55\INCLUDE\Python.h 7: Unable to open include file 'patchlevel.h'

indicates that the error (unable to open file) was introduced by the file python.h in line 7. You might not have included all those header files, but your python.h might.

However,

  1. try to find out where those files are stored on your computer. Then
  2. find out how to tell your compilere where to search for additional include files and provide the location you found the files. Without doing so, the compiler just looks at certain pre-configured directories which are, in your case, not sufficient.

You technically did. By including Python.h, you effectively include all the headers it is including and depending on. If those are not there, then your code cannot compile. You can find more details on how to properly build around CPython into the Introduction Guide.
