'generator' object has no attribute 'next' in disassembler, • AttributeError: 'generator' object has no attribute 'next' Hi guys, I am trying to turn this function generator into a generator object that will cycle through the tuples in this list that's is contained in object. Programming is about problem solving and problem solving involves running into a lot of problems and when I say problem solving, I mean a lot less "If Jack has 3 apples and Jill has X-n 2 apples, come up with an algorithm which sorts out a list of even numbers and every odd number produces the word 'lmao'".

You could use dir(f) to see all the methods of file object. The difference is quite similar to the difference between range and xrange.. A List Comprehension, just like the plain range function, executes immediately and returns a list.. A Generator Expression, just like xrange returns and object that can be iterated over.
