python reference tuple values code example
Example 1: what is a tuple in python
# A tuple is a sequence of immutable Python objects. Tuples are
# sequences, just like lists. The differences between tuples
# and lists are, the tuples cannot be changed unlike lists and
# tuples use parentheses, whereas lists use square brackets.
tup1 = ('physics', 'chemistry', 1997, 2000);
tup2 = "a", "b", "c", "d";
# To access values in tuple, use the square brackets for
# slicing along with the index or indices to obtain value
# available at that index.
tup1[0] # Output: 'physics'
Example 2: tuple() python
example = [1, 2, 3, 4]
# Here is a list above! As we both know, lists can change in value
# unlike toples, which are not using [] but () instead and cannot
# change in value, because their values are static.
# list() converts your tuple into a list.
tupleexample = ('a', 'b', 'c')
print(list(tupleexample))
>> ['a', 'b', 'c']
# tuple() does the same thing, but converts your list into a tuple instead.
print(example)
>> [1, 2, 3, 4]
print(tuple(example))
>> (1, 2, 3, 4)
