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)

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

After poking around a bit through the Introduction to Tkinter  I came up with the code below  which doesn t do anything except display a text field and clear it when the  Clear text  button is pushed   import tkinter as tk  class App tk Frame       def   init   self  master           tk Frame   init   self  master  height 42  width 42          self entry   tk Entry self          self entry focus           self entry pack           self clear button   tk Button self  text  Clear text   command self clear text          self clear button pack        def clear text self           self entry delete 0   end    def main        root   tk Tk       App root  pack expand True  fill  both       root mainloop    if   name         main         main

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

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 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    gt  gt  output   lt class  str  gt    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

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
