Tkinter focus_set use with grid
A newbie to Tkinter here. . . . . . I'm trying to set the focus on an Entry textbox with focus_set. I am using the grid manager. I created the same interface before using the pack() method and the focus_set worked, but now it says "AttributeError: 'NoneType' object has no attribute 'focus_set'" Below is the section of the code: # CREATES THE GUI FOR DCN INPUT def get_dcn(): master = Tk() _dcn = StringVar() label1 = Label(text="Enter DCN:",width=10).grid(row=0) txtbox = Entry(relief=SUNKEN, width=20, takefocus=1, textvariable=_dcn).grid(row=0, column=1) txtbox.focus_set() btnOK= Button(text="OK",command=assign_dcn(_dcn)).grid(row=1, column=0) btnCancel = Button(text="Cancel", command=killer).grid(row=1, column=1) master.mainloop() return Does anyone know where I went wrong?

create a text file
I'm writing a script to list all of my music files' id3 tags to a comma delimited file. The only part I'm missing seems like it should be the simplest. I haven't used Python for the last couple of years. My question is this: When I use os.open(,"w"), I get an error message,TypeError: an integer is required. Has something changed? Did I miss something??? Thanks, ---> S Cook -- http://mail.python.org/mailman/listinfo/python-list

how to get the length of a number
Can anyone tell me how to get the length of a number. I know len(string) will get the length of a string, but it doesn't like len(int). I seem to remember something like %s string. I tried to set a variable = to %s int, but that doesn't work. Is there a function I've forgotten about to convert an integer to a string?

How could I have forgotten that. Boy is my face red :) Thanks I'll try to make my next question a more intelligent one. Regards, Stan -- http://mail.python.org/mailman/listinfo/python-list
Database read and write
Ok . I know I'm talking ancient history, but some of us are stuck working with them. Is there anything for python which will ope, read, and write to a Dbase 3 or 4 file? I really need your assistance on this one. Regards, Stan -- http://mail.python.org/mailman/listinfo/python-list

Python with Eclipse
I've been trying to use Eclipse with Python on Linux for a while and have noticed something odd. After running the code or debugging a few times, its responsiveness gets really bad. Upon checking the equivalent of the task manager, I find several instances of Python running. When I kill these instances, the responsiveness comes back. I'm not sure if there is a better place to post this, but it is Python related. Is this just an issue with Eclipse or is there something else I should inspect? Any help would be appreciated.

Another Eclipse Question with Python
I followed the help instructions to set a watchpoint for a variable, or at lest I tried. When I hilight the variable and go to the run menu, the "toggle watchpoint" is grayed out and can't be selected as specified. Is this Python related only? Just wondering, I want to use the software with all of the features it allows if possible. Thanks S Cook -- http://mail.python.org/mailman/listinfo/python-list
