Getting values by pressing 'Enter' key rather than clicking a button

I have created a program in python(Tkinter) which takes username and password as input and a button which, when pressed, goes through a function which checks the username and password and further runs the program. I want that, rather than clicking the button, user presses the 'Enter' key and that does the function of the button. please help.

For me, the normal binding to a function did not work. Probably because I am using it inside a class, I used the Lambda function and it worked. Here's the code:

inp.bind('', lambda _: show())

You can bind the <Return> event on the Entry widget with some method (which will do what you want):

# binding <Return> event

import tkinter as tk
import tkinter.messagebox as msg

def show(event=None): # handler
    msg.showinfo('name', 'Your name is ' + inp.get())

m = tk.Tk()

prompt = tk.Label(m, text='Name: ')
prompt.pack(fill='x', side='left')

inp = tk.Entry(m)
inp.bind('<Return>', show) # binding the Return event with an handler
inp.pack(fill='x', side='left')

ok = tk.Button(m, text='GO', command=show)
ok.pack(fill='x', side='left')

m.mainloop()

If you want to know more about events and bindings, see this effbot's page, which is quite easy to understand.

I believe you'll want to bind the key to your handler: frame.bind('<Return>', some_handler).
