zip() function accepts multiple lists/tuples as arguments and returns a zip object, which is an iterator of tuples. Use zip() to Iterate Through Two Lists Pass both lists to the zip() function and use for loop to iterate through the result iterator. listA = [1, 2, 3, 4] listB ...
the "magicians" is a list, while the individule "magician" represent every element in the list, one everytime. The operation and access we perform to it will act on every element in the list. It's similar to the x in mathematic. The function of for loop is justrun throughall items ...
