Could you let me know how I can optimize the following code? def f(y, list_or_elem): 开发者_JS百科if getattr(list_or_elem, \'__iter__\'):
Many Java framework classes implement Iterable, however String does not. It makes sense to iterate over characters in a String, just as one can iterate over items in a regular array.
I know that Scala\'s Lists have a map implementation with signature (f: (A) => B):List[B] and a foreach implementation with signature (f: (A) => Unit):Unit but I\'m looking for something that ac
I read Why is Java's Iterator not an Iterable? and Why aren't Enumerations Iterable?, but I still don\'t understand w开发者_StackOverflowhy this:
I\'m modifying some code that calls enumerate on a list dec开发者_StackOverflow中文版lared via a list comprehension e.g.
So lets say I have an incredibly nested iterable of lists/dictionaries.I would like to print them to a file as easily as possible.Why can\'t I just redirect print to a file?
This is a problem from euler-project. No.13 import math #no.13 sum = [] number = 0 a = 3710728753390210279879799822083759024651013574025046376937677490009712648124896970078050417018260538743249861

I have a class MyMap which wraps TreeMap. (Say it\'s a collection of dogs and that the keys are strings).
Is there a method like 开发者_高级运维isiterable? The only solution I have found so far is to call
