Keep placeholder after typing and deleting something in a python Tkinter Entry?

This is my code:

date.insert(0, 'yyyy-mm-dd')
date.bind("<FocusIn>", lambda args: history_Date_Entry.delete('0', 'end'))

How can I make the placeholder visible after someone type on it and delete the text?

Solution 
  • try:
    from tkinter import *  # Python 3.x
except ImportError:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e1 = Entry(root) # dummy one
e.insert(0, 'yyyy-mm-dd')
e.bind("<FocusIn>", lambda args: e.delete('0', 'end'))
e.bind("<FocusOut>", lambda args: e.insert('0', 'yyyy-mm-dd'))
e.pack()
e1.pack()
root.mainloop()
