I’m unclear about your question. From http://effbot.org/tkinterbook/entry.htm#patterns, it
seems you just need to do an assignment after you called the delete.
To add entry text to the widget, use the insert method. To replace the current text, you can call delete before you insert the new text.

e = Entry(master)
e.pack()

e.delete(0, END)
e.insert(0, "")

Could you post a bit more code?

real gets the value ent.get() which is just a string. It has no idea where it came from, and no way to affect the widget.

Instead of real.delete(), call .delete() on the entry widget itself:

def res(ent, real, secret):
    if secret == eval(real):
        showinfo(message='that is right!')
    ent.delete(0, END)

def guess():
    ...
    btn = Button(ge, text="Enter", command=lambda: res(ent, ent.get(), secret))

Try with this:

import os
os.system('clear')

First of all, make sure the Text is enabled, then delete your tags, and then the content.

myText.config(state=NORMAL)
myText.tag_delete ("myTags")
myText.delete(1.0, END)

When the Text is “DISABLE”, the delete does not work because the Text field is in read-only mode.

You shall proceed with ent.delete(0,"end") instead of using ‘END’, use ‘end’ inside quotation.

 secret = randrange(1,100)
print(secret)
def res(real, secret):
    if secret==eval(real):
        showinfo(message='that is right!')
    real.delete(0, END)

def guess():
    ge = Tk()
    ge.title('guessing game')

    Label(ge, text="what is your guess:").pack(side=TOP)

    ent = Entry(ge)
    ent.pack(side=TOP)

    btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
    btn.pack(side=LEFT)

    ge.mainloop()

This shall solve your problem

if none of the above is working you can use this->

idAssignedToEntryWidget.delete(first = 0, last = UpperLimitAssignedToEntryWidget)

for e.g. ->

id assigned is = en then

en.delete(first =0, last =100)

def clear():                                                                           
        global input                                                                    
        abc =  
        input.set(abc)                                                                     

root = Tk()                                                               
input = StringVar()                                                             
ent = Entry(root,textvariable =                                       input,font=('ariel',23,'bold'),bg='powder                            blue',bd=30,justify='right').grid(columnspan=4,ipady=20)                       
Clear = Button(root,text="Clear",command=clear).pack()                       

Input is set the textvariable in the entry, which is the string variable and when I set the text of the string variable as “” this clears the text in the entry

Simply define a function and set the value of your Combobox to empty/null or whatever you want. Try the following.

def Reset():
    cmb.set("")

here, cmb is a variable in which you have assigned the Combobox. Now call that function in a button such as,

btn2 = ttk.Button(root, text="Reset",command=Reset)

If in case you are using Python 3.x, you have to use

txt_entry = Entry(root)

txt_entry.pack()

txt_entry.delete(0, tkinter.END)

if you add the print code to check the type of real, you will see that real is a string, not an Entry so there is no delete attribute.

def res(real, secret):
    print(type(real))
    if secret==eval(real):
        showinfo(message='that is right!')
    real.delete(0, END)

>> output: <class 'str'>

Solution:

secret = randrange(1,100)
print(secret)

def res(real, secret):
    if secret==eval(real):
        showinfo(message='that is right!')
    ent.delete(0, END)    # we call the entry an delete its content

def guess():

    ge = Tk()
    ge.title('guessing game')

    Label(ge, text="what is your guess:").pack(side=TOP)

    global ent    # Globalize ent to use it in other function
    ent = Entry(ge)
    ent.pack(side=TOP)

    btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
    btn.pack(side=LEFT)

    ge.mainloop()

It should work.

From my experience, Entry.delete(0, END) sometimes didn’t work when the state of entry widget is DISABLED. Check the state of Entry when Entry.delete(0, END), doesn’t work and if the value of entry widget remains, call entry.update() to reflect the result of delete(0, END).

You can Use Entry.delete(1.0, END)
it deletes every thing in the entry field, if u use only Entry.delete(1.0)it deletes the last word you inputed ->Example text to ->xample text
