How to save a button press (from an array of buttons) to tkinter, why is only the last one saved?

Question

Python

import calendar
import datetime
from functools import partial

def changeBut (event, but, i):
    but["bg"] = "green"
    p.append(i)
    print(i)
    print(p)
def left_click(event, i):
    print(but.text[i])
p = []
m = datetime.date.today()
dof = ['Vs DSdsada','DDDa aaAAAA']
a = calendar.monthrange(m.year, m.month)
root = Tk()
i = 0
s = a[1]+1
de = []
while i < s:
    if i == 0:
        Label(root, text = '').grid(row = 1, column = i+1)
        i+=1
        continue
    Label(root, text = str(i)).grid(row = 1, column = i+1)
    i+=1
i = 0
myrow = 0
while i<s:
    if i == 0:
        Label(root, text=dof[0]).grid(row = 2, column = i+1)
        i+=1
        continue
    but = Button(root, text=i, textvariable=i)
    but.bind("<Button-1>", lambda event, but=but: changeBut(event, but, i))
    #but.bind('<Button-1>', left_click(event, i))
    but.grid(row = 2, column = i+1)
    i+=1
root.mainloop()

in the 'p' array, you need to save the 'textvariable' of the pressed button
for me so far like this:

Answer 1

Since the variable i is not a lambda parameter, after the end of the loop, all lambdas will have one last value i = 32
Try this:
but.bind("", lambda event, but=but, i = i: changeBut(event, but, i ))
