overview of tuple()
The tuple() function is used to create tuples. A tuple is an immutable sequence and it can also be created by using round brackets.
use of tuple()
The tuple() function is used to create tuples out of iterables like lists.
# use of tuple() function
emptyTuple = tuple()
listTuple = tuple([1, 2, 3, 4])
stringTuple = tuple('Python')
dictTuple = tuple({1: ' first', 2: 'second'})
print(emptyTuple)
print(listTuple)
print(stringTuple)
print(dictTuple)
Four tuples are created by using the tuple() function: One empty tuple, one tuple from a list, one tuple from a string, and one tuple from a dictionary. Finally, all four tuples are printed.
Please note that only the keys of the dictionary are used for the tuple, not the values.
