What are different ways of creating a tuple?

Tuples can be created by the following ways:

1. By placing a sequence of values separated by comma within parentheses.
   Example:
   tup = (1, 2, 3)
2. By placing a sequence of values separated by comma without parentheses (parentheses are optional).
   Example:
   tup = 1, 2, 3
3. By using the built-in tuple type object (tuple( )) to create tuples from sequences as per the syntax given below:
   T = tuple(<sequence>)
   where sequence can be any type of sequence object like strings, tuples, lists, etc.
   Example:
   tup = tuple([1, 2, 3, 4])
