How to hide password characters?

I created a simple program in which I added username and password entry (no GUI) by using an if else conditional expression.
When I type the username in program, it appears as simple text, and that's ok.
But when I type in the password field, it also appears as simple text.
I want the password instead to display * like all login prompts.

How do I change the password field to show => *****?

usr = (str(input('USERNAME : ')))
if usr == 'python':
  password = (str(input('PASSWORD : ')))
  if password == 'root':
    print ('login succesfull')
  else:
    print ('wrong password')
else:
  print ('wrong username')
