How is a tuple containing just one element created ?

There are two ways of creating single element tuple:

1. By enclosing the element in parentheses and adding a comma after it.
   Example: t = (a,)
2. By using the built-in tuple type object (tuple( )) to create tuples from sequences:
   Example:
   t = tuple([1])
   Here, we pass a single element list to the tuple function and get back a single element tuple.
