The ith element of the tuple is created using the ith element from each of the iterables.list_A = [1, 2, 3, 4] listB = ['a', 'b', 'c', 'd'] zl= zip(listA, listB) print zlOutput:[(1, a), (2, b), (3, c), (4, d)]Zip in Python 3In Python 3, when we execute the above code, we wont get the same result. Instead, well get:zip object at 0x01055440Try it out!This is because zip methods returns a zip object instead of a list. This zip object is an iterator.In other words, returns a single iterator object, having mapped values from all the containers.So in order to get the values, we either convert the zl ( from the above code) to list, set or anything.listA = [1, 2, 3, 4] listB = ['a', 'b', 'c', 'd'] zl= zip(listA, listB) zl = list(zl) print(zl)Output:[(1, a), (2, b), (3, c), (4, d)]UnZipping in PythonUnzipping means converting the zipped values back to the individual self as they were. This is done with the help of * operator.So now, if we want to put the old values into listA and listB from zipped list zl, then we have to unzip zl.listA = [1, 2, 3, 4] listB = ['a', 'b', 'c', 'd'] #zip listA and listB and put it in one list zl zl= zip(listA, listB) zl = list(zl) print(zl) #unzip zl and put the values back to listA and listB listA, listB = zip(*zl) print(listA) print(listB)Output:[(1, a), (2, b), (3, c), (4, d)] (1, 2, 3, 4) (a, b, c, d)To clearly understand the difference, we take two new variables and put the unzipped data in that.listA = [1, 2, 3, 4] listB = ['a', 'b', 'c', 'd'] zl = zip(listA, listB) zl = list(zl) print(zl) listC, listD = zip(*zl) print(listC) print(listD) print(listA) print(listB)Output:[(1, a), (2, b), (3, c), (4, d)] (1, 2, 3, 4, 5) (a, b, c, d, e) [1, 2, 3, 4, 5] [a, b, c, d, e]As you can see, listA and listB are lists and listC and listD are shown as tuples shown as the output. Thats the only minor difference.With this, we come to an end of this Zip Function in Python article.
