Suppose I have a dictionary that has items that need to be parsed or 'fixed' in some way:

```
testDict = {'05071': ['Clarksville*050112', 'Coal Hill*050315', 'Hartman*050251', 'Johnson County*050441'], '41067': ['Beaverton ***410240', 'Forest Grove ***410241', 'Hillsboro ***410243', 'King City ***410269', 'North Plains ***410270', 'Sherwood ***410273', 'Tualatin ***410277'],...}

```

I want to replace any of the value list items that have " \*\*\*" with "\*":

```
for k, v in testDict.items():
  for item in v:
    if " ***" in item:
        item = item.replace(" ***", "*")

```

That would return, for example an item: `'Sherwood*450184'` instead of `'Sherwood ***410273'`. My question now is, how do I replace the old `item` with the new `item` in `testDict`?
