Replacing list item with contents of another list

Question

Similar to this question, but instead of replacing one item with another, I\'d like to replace any occurrences of one item with the contents of a list.

orig          


        

Answer 1

No need for anything fancy:

desired = orig[:2] + repl + orig[3:]

To find 2 you can search for orig.index('c').

x = orig.index('c')
desired = orig[:x] + repl + orig[x+1:]

if repl is not a list, just use list(repl)
