Answer:

See the explanation  

Explanation:

tkinter toolkit                                            

• Easy to use
• Easy to learn
• Easy to debug
• Good for simple tasks
• TkInter 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 tkinter
• GUI is clearer in display than tkinter
• Widgets are more interactive than that of tkinter
• size of a PyQt program is larger than that of tkinter
• uses 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()
