        I want to use WHILE LOOP in the first one and in the second question we need to take a string 'foobar' and then we should make the prog to get the following out put

        let me tel u the exact question

        Write a small Python program that generates the list of all pairs of characters c and

        its doubling 2 c, where c moves through all the letters of the string "foobar" and prints it out.

        The result will look like:

        [(’f’, ’ff’), (’o’, ’oo’), (’o’, ’oo’), (’b’, ’bb’), (’a’, ’aa’), (’r’, ’rr’)]

        thatz the exact 2nd question

        also let me know aboutthe first one

        thanks allot

        Tips:

        1.

        range can be stepped down in reverse order

        ex ->

        >>> range(10, 1, -2)

        [10, 8, 6, 4, 2]

        2.

        you can directly get chars of string.

        ex ->

        >>> [i for i in 'foobar']

        ['f', 'o', 'o', 'b', 'a', 'r']

        also

        >>> 2 * 'f'

        'ff'
