The Entry widget is used to create a single line text-box to the user to accept a value from the user.
We can use the Entry widget to accept text strings from the user. It can only be used to get one line of text from the user. If you want to use multiple lines of text, use the text widget.

Here is the syntax to create the entry widget −
w = Entry( master, option, ... )

Code Examples
from tkinter import *
def getdata():
print(entry1.get())
print(entry2.get())
root = Tk()
root.geometry("200x150")
frame = Frame(root)
frame.pack()
entry1 = Entry(frame, width = 20)
entry1.insert(0,'Username')
entry1.pack(padx = 5, pady = 5)
entry2 = Entry(frame, width = 15)
entry2.insert(0,'Password')
entry2.pack(padx = 5, pady = 5)
Button = Button(frame, text = "Submit", command = getdata)
Button.pack(padx = 5, pady = 5)
root.mainloop()
