Getting the index list and tuples list.index tuple.index

list and tuple have an index-method to get the position of the element:

alist = [10, 16, 26, 5, 2, 19, 105, 26]
# search for 16 in the list
alist.index(16) # 1
alist[1]        # 16

alist.index(15)

ValueError: 15 is not in list

But only returns the position of the first found element:

atuple = (10, 16, 26, 5, 2, 19, 105, 26)
atuple.index(26)   # 2
atuple[2]          # 26
atuple[7]          # 26 - is also 26!
