title: How to build multiple .py files into a single executable file using pyinstaller?
body: <p>I have made a small PyQt application containing 5-6 .py files. Now I want to build and compile them into a single main file, meaning it has to operate from one main window exe.</p>
  <p>My .py files are connected with each other successfully. I have used pyinstaller to make the executable file, but the problem is I built each .py file into its own .exe file. But I want to make a single .exe file through which all the .py files can be used.</p>
  <p>How to build all .py files into a single .exe file?</p>
