Linking certain filenames in a directory and a dictonary?

[Kase]

Hi. I'm trying to get my feet wet with programming and keep hitting some brick walls.

I basically want to look in a folder for certain filenames. If the files are there, I would like the term linked to the filename to be in a listbox.

I thought a dictionary would work:

dataset = { "File1.txt":"Picotiter Plate",
                    "File2.txt":"KeyPass Wells",
                    "File3.txt":"Reagent Lot numbers",
                    "File4.txt":"Insert other trackable item"}

Basically, a user selects a certain folder (using tkFileDialog.as kdirectory(). I then need a check to see if the filenames (the first part of the dictionary) are present. Then I would like the second part of the dictionary to be in the listbox.

I'm using tkinter.


Here's what I have:

#! /usr/bin/env python
from Tkinter import *
import tkMessageBox
import tkFileDialog
import os

class FileHandling:

    def datasets(self):
          dataset = { "File1.txt":"Picotiter Plate",
                    "File2.txt":"KeyPass Wells",
                    "File3.txt":"Reagent Lot numbers",
                    "File4.txt":"Insert other trackable item"}
          

class GUIFramework(Frame):
    """This is the GUI"""
    
    def __init__(self,master=None):
        """Initialize yourself"""
        
        """Initialise the base class"""
        Frame.__init__(self,master)
        
        """Set the Window Title"""
        self.master.title("454 Run Tracer")
        """Display the main window
        with a little bit of padding"""
        self.grid(padx=15, pady=15,sticky=N+S+E+W)
        self.CreateWidgets()

    def pathentry(self):
        path = tkFileDialog.askdirectory()
        path_selectedFolder = "%s" % path
        print "You chose %s" % path
        for file in os.listdir("%s" % path):
            self.FileList.insert(END, file)
        if FileHandling.dataset() in os.listdir("%s" %path): #Having trouble #here
           "" self.DataTypes.insert(END, WHAT GOES HERE?""") #Trouble here #also
                                                                     

    
       
    def CreateWidgets(self):
        

        """Create the buttons """
        self.Instructions = Label(self, text="First, select a folder --->")
        self.Instructions.grid(row=0, column=0)
        self.btnDirectory = Button(self, text= "Select Run Folder", fg= 'blue', command=self.pathentry)
        self.btnDirectory.grid(row =0, column = 2, columnspan= 4, sticky = E+W)
        self.btnSelectAll = Button(self, text="Select All", fg='blue') #command = self.select_all
        self.btnSelectAll.grid(row=8, column = 2)
        self.btnCollectData = Button(self, text = "Collect Data" ,fg= "blue") # command = self.CollectData)
        self.btnCollectData.grid(row =8, column = 3)


        """Create a frame to separate the buttons from the listbox"""
        spaceframe = Frame(self, height= 5)
        spaceframe.grid(row=4, column = 1)
        
        self.FileListLabel = Label(self, text= "Select Data to Collect: ")
        self.FileListLabel.grid(row = 3, column = 0)
        """Create the Listbox Widget"""
        scrollbarV = Scrollbar(self, orient = VERTICAL)
        scrollbarH = Scrollbar(self, orient = HORIZONTAL)
        self.FileList= Listbox(self, selectmode= MULTIPLE
                            , width= 40

        self.DataTypes.grid(row=5, column = 3, columnspan=6, sticky= N + W + S + E)

if __name__ == "__main__":
    guiFrame = GUIFramework()
    guiFrame.mainloop()

Any help would be very appreciated. I'm trying to clear out the cobwebs.

Thanks

I modified some parts of the posted code to display the information you wanted. If the file name is not in the dictionary, the text "XXX" is displayed.

#! /usr/bin/env python
from Tkinter import *
import tkMessageBox
import tkFileDialog
import os
 
class FileHandling:
    datasets = { "File1.txt":"Picotiter Plate",
                "File2.txt":"KeyPass Wells",
                "File3.txt":"Reagent Lot numbers",
                "File4.txt":"Insert other trackable item"}

 
 
class GUIFramework(Frame):
    """This is the GUI"""
 
    def __init__(self,master=None):
        """Initialize yourself"""
 
        """Initialise the base class"""
        Frame.__init__(self,master)
 
        """Set the Window Title"""
        self.master.title("454 Run Tracer")
        """Display the main window
        with a little bit of padding"""
        self.grid(padx=15, pady=15,sticky=N+S+E+W)
        self.CreateWidgets()
 
    def pathentry(self):
        path = tkFileDialog.askdirectory()
        print "You chose %s" % path
        fileList = os.listdir(path)
        for name in fileList:
            self.FileList.insert(END, name)
        dd = FileHandling.datasets
        for name in fileList:
            self.DataTypes.insert(END, dd.get(name, "XXX"))

Awesome

That worked! I modified it a little so that I didn't get a long list of 'XXX' based on what files were in the folder that didn't correlate to the dictionary.
I think it works so far:

 for name in fileList:
            self.DataTypes.insert(END, dd.get(name))

Thanks a ton!
