Mouse lib keeps dropping same error

[MLGpotato]

Hi. I have lost all my hopes fixing this issiue. Can anyone help?

import mouse
from tkinter import *
import time
import os

run = type(True)

def noclick():
    run = False
    exit()

def clicker():
    cap = float(e)
    while (run == True):
        mouse.click("left")
        time.sleep(cap)

mouse.on_double_click(lambda: exec(clicker()))
mouse.on_right_click(lambda: exec(noclick()))
print("Literaly a clicker for POPCAT")
print("Enter number (the less the faster it goes)")
print("Right click on mouse to turn the script off")
e = input("Time gaps between clicks: ")
print("Double click to activate")

Error:
mouse.on_double_click(lambda: exec(clicker()))
TypeError: exec() arg 1 must be a string, bytes or code object
