d) Frame

See the explanation  

Explanation:

tkinter toolkit                                            

Easy to useEasy to learnEasy to debugGood for simple tasksTkInter applications are simpler as compared to PyQt because it is included in standard Python distribution.Faster than PyQt.Does not have advanced widgets.No interface builder available.Free for commercial utilization.

PyQt

More flexible in terms of coding.Harder to debug as compared to tkinterGUI is clearer in display than tkinterWidgets are more interactive than that of tkintersize of a PyQt program is larger than that of tkinteruses a variety of paltform APIs and gives primary access to these APIs through a unique API.Has an interface builder that allows to design interfaces without writing any code.Has modern widgets.Due to its vast interface and several UI components it is a bit confusing to learn as compared to tkinter.Commercial license is required to release the code.Cross-platform and native GUI.

Widgets are GUI components such as buttons, labels, menus.

a) Label

This is a tkinter widget to show the text or image on the screen. It looks like a display box. The user can easily edit or update label.

For example to display a label with text "Hello World" the following chunk of code is used:

import tkinter

widget = tkinter.Tk()

label =tkinter.Label(widget, text="Hello World")

label.pack()

tkinter.mainloop()

b) Entry

This is a tkinter widget to accept the text input from user. For example if you want to get a single line text from user then you can use Entry widget. The code below displays an entry widget with the message: Enter input text: Here the user can input the text.

import tkinter

widget = tkinter.Tk()

entry = tkinter.Entry(widget)

entry.insert(0, "Enter input text:")

entry.pack()

tkinter.mainloop()

c) Button

This is a tkinter widget to add a button in an application. You can enter some text or an image in this button convey its purpose. When you click on the button a function is called or an event is emitted.

The following chunk of code displays a button with the text "Click Me" on the button.

import tkinter

widget = tkinter.Tk()

button = tkinter.Button(widget, text="Click Me")

button.pack()

tkinter.mainloop()

d) Frame

This is a tkinter widget to group together and organize other widgets and arranges their position.

The following chunk of code displays an outer frame with a label with text "parent label" and an inner frame with a label of text "child frame".

import tkinter

widget = tkinter.Tk()

frame = tkinter.LabelFrame(widget,text="parent frame")  

label= tkinter.Label(frame,text="child frame")

frame.pack(padx=10, pady=10)

label.pack()

tkinter.mainloop()
