Python | Pair and combine nested list to tuple list. You can not add, change, remove items (elements) in tuples. We can use that to add single element in numpy array. Because some downstream code may be expecting to handle tuple and the current list has the values for that tuple. Consider you have a dictionary as follows: Because in case of lists, we have square brackets around the list elements. Python Set add() The set add() method adds a given element to a set. But for that we need to encapsulate the single value in a sequence data structure like list and pass a tuple of array & list to the … You can also do tuple(sum(aa, bb) for aa, bb in zip(a, b)) to unpack the two elements into separate variables. In this, we add dictionary to different tuple and then add the old tuple to this tuple and form new tuple. – Martijn Pieters ♦ May 14 '13 at 16:46 Python - Convert Tuple String to Integer Tuple.
