As the title suggests, I'm trying to make a counter with IntVar(),so I've tried this.

from tkinter import *

def main():
    root = Tk()
    root.resizable(FALSE, FALSE)
    root.geometry('200x50')
    root.title('Home')

    #starts here
    var = IntVar()
    text = 'Count: ' + str(var.get())

    b1 = Button(root, text='Test', command=fun)
    b1.pack()
    l1 = Label(root, text=text)
    l1.pack()

    mainloop()

def fun():
    for i in range(1, 11):
        print('test')

main()

But I got confused, I want to make it count the printings and show the value in the label.

Any help would be appreciated.

If you are trying to count the number of times 'test' is printed, you can update the l1 widget with l1['text'] = var after updating. To update, you can fetch the variable of intvar and then add 1 to it. Here's some code:

from tkinter import *

def main():
    root = Tk()
    root.resizable(FALSE, FALSE)
    root.geometry('200x50')
    root.title('Home')

    #starts here
    var = IntVar()
    text = 'Count: ' + str(var.get())

    b1 = Button(root, text='Test', command=lambda: fun(l1, var))
    b1.pack()
    l1 = Label(root, text=text)
    l1.pack()

    mainloop()

def fun(l1, var):
    for i in range(1, 11):
        print('test')
        var.set(var.get()+1)
        l1['text'] = 'Count: ' + str(var.get())

main()
