python tuple methods

1#a tuple is basically the same thing as a
2#list, except that it can not be modified.
3tup = ('a','b','c')

1a=(1,2,3,4)
2print(a[-3])

1example = [1, 2, 3, 4]
2# Here is a list above! As we both know, lists can change in value
3# unlike toples, which are not using [] but () instead and cannot
4# change in value, because their values are static.

6# list() converts your tuple into a list.
7tupleexample = ('a', 'b', 'c')
