how do you access info in tuple in python 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)
