  Using the Python zip() Function for Parallel Iteration       Python’s zip() function creates an iterator that will aggregate elements from two or more iterables. You can use the resulting iterator to quickly and consistently solve common programming problems, like creating dictionaries . In this tutorial, you’ll discover the logic behind the Python zip() function and how you can use it to solve real-world problems. By the end of this tutorial, you’ll learn: How zip() works in both Python 3 and Python 2 How to use the Python zip() function for parallel iteration How to create dictionaries on the fly using zip()     Understanding the Python zip() Function zip() is available in the built-in namespace . If you use dir() to inspect __builtins__ , then you’ll see zip() at the end of the list: >>> dir ( __builtins__ ) ['ArithmeticError', 'AssertionError', 'AttributeError', ..., 'zip'] You can see that 'zip' is the last ent...
