I have a code which I am trying to open different files from different folders and use those files to plot a graph. I am using askdirectory in tkinter and storing the filenames into a listbox.
Python
<        def ask():
            global path
            path = filedialog.askdirectory() # select directory 
            statusbar1.config(text=path) # update the text of Label with directory path 
            x=next(os.walk(path))[2] # list of files 
                                       
            for each_item in range(len(x)):          
                listb.insert(tk.END, x[each_item])
                listb.itemconfig(each_item, bg = "#8c92ac",fg= "#161327")> "> 
Then I want to choose a filename from the listbox and use the content to plot a graph.

Python
<
        def paths_selected():
            global paths,spectrum_data, xaxis, var, path, filenames
            filenames = [listb.get(i) for i in listb.curselection()]>

What I have tried:
Function "paths_selected" is operated by a button (browse). This will populate the listbox from files from any folder everytime I click the browse button. But I can only use files from one directory to plot the graph. I want to be able to choose a file from a different directory and use both files to plot the graph. Any ideas of how to do that?

You could use two listboxes, or do two calls to askdirectory and store the complete path in the listbox.

Is there a way to use the same listbox? Because eventually I would like to navigate through directories and use files from anywhere. Not essentially just two. Thanks
