I'm trying to create a drop down menu using a string from a file which I;m reading in. That part works. However, I'm trying to build the GUI using tkinter and it will only open in debugging mode. When it does open, it works. What is going on?

master = Tk()

with open('player_names.csv','r') as csvfile:
 plots = csv.reader(csvfile, delimiter=',')
 next (plots)
 for row in plots:
 number.append((row[0]))
 first.append(row[1])
 last.append(row[2]) 

variable = StringVar(master)
variable.set(number[0]) # default value

w = OptionMenu(master, variable, *number)
w.pack()

def ok():
 print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

When it works correctly, the GUI opens and there is a little drop down menu with all of the values from number[]. It just won't open.

  What are you running to start it, both ways? Maybe you are running it from different working directories so it is not finding your csv.

  @MattClark I'm using Wing. I'm just running it like I always do. I built another GUI with tkinter and it worked just fine.

  Maybe simply adding some logging statements to see the working directory of your application, and if it loaded the file properly?

  @MattClark the file is loading correctly. If I manually define the string, it still wont open when I just run it, but will in debug mode.

  @andrewalmosthasaclue I have tested your code in my Wing IDE (after adding the missing declaration of number, first, last) and it works whether it is in debug mode or not.
