    So basically if you want a particular array which you don't want to change overtime then, it is recommended to use Tuple ( as it takes less memory ).
    Tuples:
    1. Index
    2. Count
    List:
    1.append
    2.remove
    etc..

    analogy: 1:57 2:55 3:25
    [], {}, (): 4:22 5:00
    list methods vs tuple lists (inbuilt): 5:16(11) 5:45(2)
    access but cannot add: 6:05
    tuple is unchangeable: 6:20 (immutable) 16:15
    list can be changed: 6:29 (mutable)
    why?: 9:08 9:33 10:05 10:55 11:15
    hidden benefit of tuple: 17:25
    s.__sizeof__(): 17:46
    summary: 18:57 (use tuple when have huge data and remains to be unchanged)
    list vs set vs tuple:
    import string
    s = string.ascii_letters
    l = list(s)
    ss = set(s)
    t = tuple(s)
    print(s)
    print('as list {}'.format(l))
    print('as set {}'.format(ss))
    print('as tuple {}'.format(t))
    Output: (set is unordered and random)
    abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
    as list ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']
    as set {'Q', 'e', 'x', 'V', 'X', 'Y', 'T', 'E', 'f', 'u', 'R', 'y', 'k', 'S', 'L', 'U', 'v', 'q', 'z', 'c', 'i', 't', 's', 'H', 'K', 'B', 'M', 'a', 'r', 'd', 'D', 'b', 'l', 'C', 'W', 'F', 'w', 'j', 'g', 'I', 'A', 'h', 'J', 'o', 'G', 'P', 'Z', 'p', 'N', 'm', 'n', 'O'}
    as tuple ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z')

    How do you get all functions of a data type listed out as sir did at 5:12? Is there some specific key combination that one needs to press?

    11:40 we dont need to convert it to list first. tuple(s) also works!

      Not sure I understood. In that min we only explain how we can convert tuples to list.
