I have to use python because it will be part of existing python code.

The concept seems simple, just combine dev#s that have devTypes, but the solution eludes me.
Below is the monstrosity that I tried and it fails miserably. In the below example 'regressionList' corresponds to the above sample input.
Code:def writeTest(regressionList):
# extract all cellNames
cellsToPlace = []
for test in regressionList:
if test[0] not in cellsToPlace:
cellsToPlace.append(test[0])
for cell in cellsToPlace:
devTypes = []
for test in regressionList:
if test[0] == cell and len(test) > 1:
devTypes.append(test[2])
print(cell,devTypes)
