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 question
i think that first i woulf take a string 'foobar'
convert it into a list
take itz length
n then do indexing
and then multiply using for loop

herez my code

a='foobar'
b=list(a)
print b
['f','o','o','b','a','r']

c=len(b)
6


thatz where i am
now i wana do the indexing of each character so that i use for loop n multply each character with 2


waiting for ur reply
