I am using Python38. I have been assigned to write a gui to edit the configuration ini file for an existing program. I have cobbled together a program which works fairly well, but when I save back to the ini file, quotes and spaces are added. My question is how do I save the text back to the ini file in the original format, ie. no extra quotes, spaces, etc...
