Python iterator and generator, python Generator I. iterator) In Python, A for loop can be used for any type in Python, including list and ancestor. In fact, a for loop can be used for any "iteratable object", which is actually an iterator. The iterator is an object that implements the iterator protocol. In Python, The iterator Protocol means that objects with the next method will move forward to the next re

In ios5, udid is no longer recommended. In future versions, this function may disappear. So we need to find a replacement method that uniquely identifies a device. Generally, the hardware has a unique identifier, so we can replace the udid with the hardware information, and the MAC address on the hardware can achieve this purpose. The following function returns a string of the XX: XX type (12 hexadecimal numbers) #include Source code: http://iphonedevelopertips.com/device/determine-mac-addre

Python masters road [9] python-based iterator and generator, python GeneratorIterator and Generator 1. iterator An iterator is a way to access collection elements. The iterator object is accessed from the first element of the set until all elements are accessed. The iterator can only move forward without moving back, but there is nothing to do with it, because people seldom go back on the way of iteration.
