Question

It's my first time trying tkinter and I can't get over this error. Can someone tell me what's wrong with it and suggest a fix?

I get TypeError: repip() takes exactly 1 argument (0 given) error.

   pool = ThreadPool(int(Thread))
   pool.map(repip, file)
   pool.close()

      entry1.insert(END, filepath)

    except:
        pass


label = Label(main_window, text="Select domain list")
label.grid(row=0, sticky=W, pady=3, padx=3)

entry1 = tk.Entry(main_window, width=50)
entry1.grid(row=1, sticky=W, pady=3, padx=3)

ttk.Button(main_window, text="Browse", command=open_file).grid(row=1, column=1, sticky=W, pady=2)
ttk.Button(main_window, text="Start", command=repip).grid(row=2, column=1, sticky=W, pady=2)

listbox = Listbox(main_window, width=50, height=20)
listbox.place(x=2, y=60)

scrollbar = Scrollbar(main_window, orient="vertical", command=listbox.yview)
scrollbar.place(x=290, y=60, height=323)
listbox.config(yscrollcommand=scrollbar.set)

tk.mainloop()

The second argument for pool.map is an iterable, like a list. Wrap around the file in square brackets and it should work:

pool.map(repip, [file])
