如何将Tkinter条目从字符串转换为整数

Question

I am making an auto clicker which asks two questions, delay and clicks per second. But when I try to make the input of the entry go to the code that says how much clicks per second it can't because it says

Traceback (most recent call last):  
    clicks = int(entry) 
TypeError: int() argument must be a string, a bytes-like object or a number, not 'Entry'

Here is the code:

import pynput
import time
import tkinter as tk
root = tk.Tk()
Height = 500
width = 600





def test_function(delay):
    from pynput.mouse import Button,Controller
    mouse = Controller()
    time.sleep(float(delay))
    mouse.click(Button.left, (int(clicks)))

canvas = tk.Canvas(root, height=Height, width=width)


canvas.pack()
entry = tk.Entry(root)
entry.place(relx=0.2, rely=0.21)
entry2 = tk.Entry(root)
entry2.place(relx=0.4, rely=0.4)


label = tk.Label(root, text="Tech AutoClicker")
label.place(relx=0.4, rely=0)
label2 = tk.Label(root, text="Clicks per sec:")
label2.place(relx=0.02, rely=0.2,)
label3 = tk.Label(root, text="Delay until starting (in seconds):")
label3.place(relx=0.02, rely=0.4)
button = tk.Button(root, text="Start Auto clicker", bg="#84f47c", fg="green", command=lambda: test_function(entry2 and entry.get()))
button.pack()
clicks = int(entry)
root.mainloop()

Answer 1

Your entry variable holds an object of the widget class Entry . You need to get the text value of the widget, using its get() method and then pass it to int() function:

clicks = int(entry.get())

In your example, in the line that you try to get the text of the Entry , it will have no value (empty string) so it won't be able to be converted to int.

This is an example of how you could use the Entry widget properly:

import tkinter


def fun():
    clicks = int(entry.get())
    print(clicks)


root = tkinter.Tk()

button = tkinter.Button(root, text='click me', command=fun)
button.pack()

entry = tkinter.Entry(root)
entry.pack()

root.mainloop()

The import statement from tk is taken out and put at start of the script as the python styling convetion here subscribes. Removing clicks and lambda functions made when mouse is on the botton autorun your scripts output.

import tkinter as tk
import pynput, time
from   pynput.mouse import Button,Controller

def test_function():
    mouse = Controller()
#    time.sleep(float(delay))  # if delay is set to e.g. 2.5. You get results after you close the window.
    mouse.click(Button.left, 1)   # on MacOS 1= 2.
    print ('User-input 1: "%s" , Ui2: "%s".' % (e1.get(), e2.get()))

# Main GUI
root   = tk.Tk()
Height = 500
width  = 600

canvas = tk.Canvas(root, height=Height, width=width)
canvas.pack()

label = tk.Label(root, text="Tech AutoClicker")
label.place(relx=0.4, rely=0)

# GUI entity 1 - user input
label2 = tk.Label(root, text="Clicks per sec :")
label2.place(relx=0.02, rely=0.2)
e1 = tk.Entry(root)
e1.place(relx=0.2, rely=0.21)
#print ('2 : %s' % e1)

# GUI entity 2 - user input
label3 = tk.Label(root, text="Delay until starting (in seconds) :")
label3.place(relx=0.02, rely=0.4)
e2 = tk.Entry(root)
e2.place(relx=0.4, rely=0.4)

# GUI entity 3 - button
button   = tk.Button(root, text="Start Auto Click", bg="#84f47c", fg="green", command=test_function)
button.pack()

root.mainloop()

The answer from elgaspar will work if clicks = str(entry) :

import tkinter

def fun():
    clicks = str(entry)
    print(clicks)

root = tkinter.Tk()

button = tkinter.Button(root, text='click me', command=fun)
button.pack()

entry = tkinter.Entry(root)
entry.pack()

root.mainloop()

Subclass the Entry widget and use the 'get' method:

class IntEntry(tkinter.Entry):
    def get(self):
        val = super().get()
        return int(val)

entry = IntEntry(root)
entry.pack()

# type number in

my_number = entry.get()

Don't forget to handle cases where the user did not put in an integer.
