Sample sqlite databases for use in python
Hello I am making a data management program and although i can make my own databases I would like a couple sample ones to check out. Of course I searched on google for sample db's and I downloaded some but they are not working and I keep getting: File is not a database or encrypted The error is not exactly like that but it does say that it may be encrypted or not a database. I want the end user to take a database and load it in to my program but I dont wont this happening even if the file is a sqlite3 one as well. -- https://mail.python.org/mailman/listinfo/python-list

Syntax Highlighting in a tkinter Text widget
Hey guys Im working on an open source text editor(https://github.com/nicodasiko/Text-Config-2) and I would like to add syntax highlighting(mainly for python code). I have built the editor in python and the text input is a Text tkinter widget. I know how to add tags and highlight things but Im not sure on how to constantly update the highlighting. -- https://mail.python.org/mailman/listinfo/python-list
How to not enable a user to close the root tkinter window
I have a project I am working on(https://github.com/nicodasiko/Article-Grab) which grabs info from the internet then displays it on the screen. It is a multithreaded program so as the function that retrieves the data from the internet there is also another function running in parallel which updates a ttk loading bar. Pretty simple multi threaded stuff. But I found out that the user can close the window whilst the threads are running which generates an error and is not healthy. Is there a way I can make the root tkinter window not close whilst the threads are running. I did this with the search bar and search button. Or can I safely stop the running threads and make them drop everything error free? Any help will be apreciated! -- https://mail.python.org/mailman/listinfo/python-list

Tkinter frame reset
Ok so I am working on a little project and I cant seem to solve something with it. I have a label and then a clear button and I want all the numbers in the label to clear when I push the button. This button is on a separate frame to the buttons. I would like to clear the frame and then set all the widgits back to how they were one you first open the app(Label being blank). I have tried to destroy it with frame.destry() and then try re create it in a function but it never recreates its self. Also when I tried grid_forget() on it, it never came back either when I tried to frame it and then grid it back on there. I can clear the label by just adding a long blank string to it to overwrite the numbers behind because I would like to have the user add more numbers in there like starting fresh. This long blank string wont work because the buttons add on to the existing string so the label keeps getting updated with the new buttons pressed. I tried to remove the label but that never came back either. Please help me with trying to clear the label or the whole window back to its original blank settings -- https://mail.python.org/mailman/listinfo/python-list
Tkinter menu crash
Ok so the first part of the program(until the start of the menu) worked fine. It ran and did what I wanted it to do. I wanted to then implement a new menu(for practise) and then it crashes.

(also tips on the code will be appreciated and I gave just started Tkinter programming) Here is the code: from Tkinter import * import tkMessageBox as tm def submit(): #message box with yes no tm.askyesno(title='Submit Text', message='Are you sure') def info(): tm.showinfo(title='About', message='Just a test Tkinter UI sample') #getting the text from the entrybox and #packs it into a label mtext = text.get() label1 = Label(app, text=mtext) label1.pack() #root window setup root = Tk() root.geometry('480x480+200+200') root.title('Basic Tk UI') #frame set up app = Frame(root) app.pack() #variable and entry box set up text = StringVar() entry = Entry(app, textvariable=text) entry.pack() #button set up button1 = Button(app, text='Submit text', command= submit) button1.pack() #menu construction menubar = Menu(root) filemenu = Menu(menubar) filemenu.add_command(label='About', command= info) filemenu.add_command(label='Quit', command= root.destroy) filemenu.add_cascade(label='TK UI Sample', menu=filemenu) root.config(menu=menubar) #loop to listen for events root.mainloop() -- https://mail.python.org/mailman/listinfo/python-list
Re: Tkinter menu crash
Ok so I am on 2.7.8. What x.y.z version of Python. How did you run it, exactly? Adding filemenu as a submenu of filemenu leads to infinite loop regress. On 3.4.1 with tcl/tk 8.6, this does not crash, but it might on an earlier version of Python and tcl/tk. Since menubar is left empty, it is not displayed. Fix both problems with menubar.add_cascade(label='TK UI Sample', menu=filemenu) root.config(menu=menubar) Yeah this fixed the problem. So the main menu object needs to be cascade instead of the filemenu. Will this need to be done every I create a new menu? and ran -- no crash, no error message, no menu. I entered text into box, clicked Submit text, and OK on popup, and nothing happens. Im not quite sure what is happening here. Oh I just looked at the code and the part that sends the entry box text is in the wrong place or must have been unindented I have fixed this now and it works great. -- https://mail.python.org/mailman/listinfo/python-list
Re: Tkinter menu crash

Html Parsing stuff
Ok i get the basics of this and i have been doing some successful parsings and using regular expressions to find html tags. I have tried to find an img tag and write that image to a file. I have had no success. It says it has successfully wrote the image to the file with a try... except statement but when i try to open this it says that the image has like no been saved correctly or is damaged. This was just reading the src attribute of the tag and trying to save that link to a .jpg(the extension of the image). Ok so i looked deeper and added a forward slash to the url and then added the image src attribute to it. I then opened that link with the urllib.urlopen() and then read the contents and saved it to the file again. I still got the same result as before. Is there a function in beautiful soup or the urllib module that i can use to save and image. This is just a problem i am sorting out not a whole application so the code is small.

If you need the source code i am happy to give it to you. Thank you for your help I am using python 2.7.7 and i have come up with away but there is still possible errors for this. What i did was i this #checks if the user input is an integer value def checkint(a): if a.isnumeric(): return True else: if a.isalpha(): return False else: return True The parameter a is the users input by the raw_input function. I first test if it is normal int with the isnumeric function. Unfortunately this function picks up the decimal as false. This means if the user inputs a float it has to be false. I then test if this input has any alphabetical characters if it does not the user could have only entered something like 12.5 oppose to abc.d. This method works fine and it i have tested it and it works fine. if incase this input did have a letter it would be picked up by the isalpha function. There is one annoying error doing it this way and that is if you enter 12.ab or ab.12 it will say that it is okay.
