Hi, When I learn for loop with below link: http://www.shutupandship.com/2012/01/understanding-python-iterables-and.html
it has such explanation: \\\\\\\\\ for loop under the hood First let's look at the for loop under the hood. When Python executes the for loop, it first invokes the __iter__() method of the container to get the iterator of the container. It then repeatedly calls the next() method (__next__() method in Python 3.x) of the iterator until the iterator raises a StopIteration exception. Once the exception is raised, the for loop ends. \\\\\\\\\ When I follow a list example from the above link, and one example of myself: ////////// xx=[1,2,3,4,5] xx.next --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-76-dd0716c641b1> in <module>() ----> 1 xx.next AttributeError: 'list' object has no attribute 'next' xx.__iter__ Out[77]: <method-wrapper '__iter__' of list object at 0x000000000A1ACE08> for c in xx: print c 1 2 3 4 5 ////////////// I am puzzled that the list examples have no next method, but it can run as a for loop. Could you explain it to me the difference? Thanks, -- https://mail.python.org/mailman/listinfo/python-list
