How can I directly open a custom file with python on a double click? <p>I am programming on a windows machine and I have an app that reads file selected by the user. Is it possible to allow them to open the file directly when they double click. This needs to work when the program is "compiled" as an .exe with cxfreeze.</p> <p>What I am really asking is this: Is there a way to allow the user to double click on a custom file (.lpd) and when they do windows starts the program (a compiled cxfreeze .exe) and passes it the file path as an argument.</p>
