JavaScript learns to record Day4-map, set, and iterable[TOC]The default object representation of JavaScript {} can be thought of as a Map data structure in another language Dictionary , or a set of key-value pairs.But the JavaScript object has a small problem, which is that the key must be a string. But actually number or other data type as a key is also very reasonable.To solve this problem, the latest ES6 specification introduces new data types Map

As long as the parameters within the extend are iterable, you can also add custom iterable, open the whole.Class A (object): def __init__ (self): self.a = 0 def __iter__ (self): return to self def next: SELF.A = self.a + 1 if SELF.A >: self.a = 0 raise stopiteration ();

1) The default Inc is as follows: Copy Code code as follows: @INC: C:/perl/site/lib C:/perl/lib 2 Set up environment variable PERL5LIB to add to Inc, for example:Set Perl5lib=c:\perllibs After setting the Perl5lib as below, Copy Code code as follows: %env: perl5lib= "C:\perllibs" @INC: C:

Off Topic:Recently, because the course needs to get into the Python language. Because Java, C + +, and other strongly typed static languages have been used all the time, it is now suddenly true that Python does feel a great difference.The intuitive feeling is that in Python you can always find something that makes the code smart, concise, efficient, and aesthetically pleasing, making the beginner's process of writing the code full of surprises, and gradually becoming fond of python. And the offi

iterator it is. It only needs to obtain this iterator interface, which is the power of object-oriented. All collection classes implement the collection interface, while collection inherits the iterable interface. /** * Implementing this interface allows an object to be the target of * the "foreach" statement. * * @param In a specific implementation class (such as arraylist), an itr internal class is maintained internally, which inherits the iterat

Iterable is an interface which provides Iterator.An implementation of being one Iterable that provides an of Iterator itself: Public Interface

This function is used to traverse all elements from an iterative object iterable , and evaluates to True When each element is run as a parameter to a function object. element is preserved, while the element that is False is skipped, which is the goal of filtering unwanted elements. The parameter iterable is an iterative object, such as a list, dictionary, string, or function object with an iterator. Para

(Reproduced: http://blog.csdn.net/passionkk/article/details/49929887)In Python list,truple,str,dict these can be iterated, but they are not iterators. Why?Because there is a big difference compared to iterators, list/truple/map/dict the size of the data is deterministic, that is to say how many things are known. But the iterator is not, the iterator does not know how many times to execute, so it can be understood to not know how many elements, each call to next (), will go down a step, is inert.

In assembly languages, it is sometimes convenient to call library functions in C language. First, give a sample program: . 386 . Model flat, stdcall Option Casemap: None ; Include definition Include stdio. inc Includelib msvcrt. Lib . Data Szmsg DB "calls the puts function of C in the assembler! ", 0 . Code Start: Invoke puts, offset szmsg RET End start Is it a bit like the hello, World Program in C. How does stdio.

Python standard library: built-in function any (iterable), pythoniterable If one of all elements of an object that can be iterated is True, True is returned. Otherwise, False is returned. Or if the iteratable object is null, False is returned. This function is mainly used to determine whether the list, tuples, dictionaries, and other objects have elements that are True, improving the computing speed. The equivalent code is as follows: Def any (

Refer to official Documentation:1 Iterable is an object that can return its members . Includes sequence types (list,str,tuple) and not-sequence types (dict, file objects), objects and classed defined with an __iter__ ( ) method or a __getitem__ () methodWhen a Iterable object is passed into the ITER () method (also called the __iter__ () method), a iteratoris returned.

it is removed, then the cursor value must be reduced by one. In fact, the implementation of the iterator here is basically covered by abstractlist subclasses, such as Linkedlist,arraylist. The former does not support random access must not use the index value as the implementation of the acquisition element, otherwise the efficiency of the iterator is too low.Listiterator (extends IteratorIn addition to inheriting the Iterable interface, the list int
