How to bind mouse action over multiple entry widgets

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;

0

I'm able to bind a mouse action on a single entry widget, meaning, by default a value will be present in the entry box, if i click then the default will be removed. How would i do the same when loop is used over individual boxes. If i click on any entry box, the default value must be removed

from tkinter import *

root = Tk()

def hello(event):
 ent.delete(0, END)

for x in range(4):
 ent=Entry(root,fg="grey")
 ent.insert(0, "dd/mm/yy")
 ent.pack()

 ent.bind('<Button-1>',hello)

root.minsize(400, 400)
root.mainloop()

python tkinter

  So are you asking how to call the same callback on all entries when one of them is clicked upon? or are you asking how to bind the same command to multiple different entries

  same command to different entries over the loop

  That's because at the end of the loop, ent is the last entry widget. You could replace ent.delete(0, END) with event.widget.delete(0, END), but I'd recommend you take a look at the two answers I linked, they make a class inherited from Entry with this functionality added, which makes this a lot easier.

Your problem is that you're hardcoding ent in your callback. The event object tells you which widget received the event, so use that instead.

def hello(event):
 event.widget.delete(0, END)
