Hello,
(im using python 2.7)
I've been having some problems to return the variable from a function so
i decided to try to do it with with global variables,
but the script is not working good. I've been reading tutorials but i
just don't get how to do it and i would like to ask for some help >.<
( at the end, it's the part of the script that is not working, you can
copy it to easily understand the problem)
what i would like create a function that creates a window for taking a
choice and returns a variable in order to proceed using the choice of
that variable.
( i've removed the variable from the script posted below because i tried
to do it with the global variables )
The problem that i have using the global variables is that the:
if Prompt_Desition==1:
if os.path.exists(Script_Location+"/program-data"):
os.system("rm -r "+Script_Location+"/program-data")
print "Program-data deleted"
else:
print "No program-data"
if os.path.exists(Script_Location+"/computer-data"):
os.system("rm -r "+Script_Location+"/computer-data")
print "Computer-Data Deleted"
else:
print "No computer-data"
Prompt_Desition=0
is executed when the main_window_gui() window is closed. i don't
understand why.
It should be executed when the def cancel_label_desition() is executed.
because thePompt_desition variable changes to 1.
Also i would like to ask if is there any way to put a definition with
arguments on the command of a button?
when i do this i get errors >.<
i define message, proceed_label, cancel_label then:
b100 = Button(window1, text="Delete",command=prompt_desition(message,
proceed_label, cancel_label))
b100.pack()

Thanks so much for helping me! I appreciate it a lot !!
