# Tuples are sequence just like list
# But they can not be changed
# Uses paranthesis
# Iteration, concatenation, membership, length is possible like List

tup4 = (50,)                         # Tuple containing single value should have comma

# But this is not a tuple it will be declared like normal variable

# Operation on Tuples
