Tkinter/python: how to create a checkbutton to select all checkbuttons - python-2.7

Question

I created a list of checkboxes with Tkinter but I would like to select all checkboxes with a single checkbox.
Here is part of my code:
root = tk.Tk()
root.title("SOMETHING")
buttons=[]
#If it is checked, then run the file
def callback():
for var, name in buttons:
if var.get():
subprocess.call("python " + "scripts/" + name)
for name in os.listdir("scripts"):
if name.endswith('.py') or name.endswith('.pyc'):
if name not in ("____.py", "_____.pyc"):
var = tk.BooleanVar()
cb = tk.Checkbutton(root, text=name, variable=var)
cb.pack()
buttons.append((var,name))
def select_all():
if var1.get():
for i in cb:
i.select(0,END)
def deselect_all():
if var2.get():
for i in cb:
i.deselect_set(0,END)
var1=tk.BooleanVar()
selectButton = tk.Checkbutton(root, text="Select All", command=select_all, variable=var1)
selectButton.pack()
var2=tk.BooleanVar()
deselectButton = tk.Checkbutton(root, text="None", command=deselect_all, variable=var2)
deselectButton.pack()
submitButton = tk.Button(root, text="Run", command=callback)
submitButton.pack()
root.mainloop()
When I run the file and press "select all", I get this error: 'str' object has no attribute 'select'.
Please help thanks :)

I have reviewed your code and attached a working tkinter code. Will leave you to resolve the issue with using subprocess.
My main comment is that your use of control variable and how to use it to get and set their value was inappropriate. I have remove the unnecessary codes. Also, shown you how to extract information from your list. Hope this helps your tkinter coding journey.
Working code:
import tkinter as tk
import os, subprocess
#If it is checked, then run the file
def callback():
if var.get():
for i in buttons:
cmd = "python3 " + filedir +"/" + i[1] #Note:Runs python3 and not python2
print(cmd)
subprocess.call(cmd)
def select_all(): # Corrected
for item in buttons:
v , n = item
if v.get():
v.set(0)
else:
v.set(1)
root = tk.Tk()
root.title("SOMETHING")
filedir = 'test'
buttons=[]
for name in os.listdir(filedir):
if name.endswith('.py') or name.endswith('.pyc'):
if name not in ("____.py", "_____.pyc"):
var = tk.IntVar()
var.set(0)
cb = tk.Checkbutton(root, text=name, variable=var)
cb.pack()
buttons.append((var,name))
var1=tk.IntVar()
var1.set(0)
selectButton = tk.Checkbutton(root, text="Select All", command=select_all,
variable=var1)
selectButton.pack()
submitButton = tk.Button(root, text="Run", command=callback)
submitButton.pack()
root.mainloop()
