Merge some list items in a Python List

Question

Say I have a list like this:

[a, b, c, d, e, f, g]

How do modify that list so that it looks like this?

[a, b, c, def, g]
         


        

Answer 1

just a variation

alist=["a", "b", "c", "d", "e", 0, "g"]
alist[3:6] = [''.join(map(str,alist[3:6]))]
print alist
