Here is an example of a text box

Python Tkinter uses entry as a text box input, binds data to a text box by textvariable, and then uses the Get function to get the content. If you want enter to get the content, you need to bind <Return> event with the following code:

1  fromTkinterImport*2 defRtnkey (event=None):3     Print(E.get ())4Root =Tk ()5E =Stringvar ()6Entry = entry (root, validate='Key', Textvariable=e, width=50)7 Entry.pack ()8Entry.bind ('<Return>', Rtnkey)9Root.title ('test Enter to get text box contents')TenRoot.mainloop ()
