temporary and voluntary, and our function will revoke control in the future.
In Python, functions with this capability are called generators, which are very useful. The generator (and yield statements) was initially introduced to allow programmers to write code for the sequence of values. Previously, to implement something similar to a random number

function will reclaim control in the future.
In Python, a "function" with this ability is called a builder, and it is very useful. The generator (and yield statement) was first introduced to allow programmers to write code that produces a sequence of values more simply. In the past, to implement something like a random number

large number of next () functions in the generator table, and the for Loop will automatically start the next function, so you can use it as follows:

Comparison between the twoAn Iteration can be written as either a generator function or a coroutine generator ex

Python's nested collection types are list, tuple, set, Dict.
List: Looks like an array, but more powerful than an array, supports indexing, slicing, finding, adding, and so on.
Tuple tuples: Functions are similar to lists, but once generated, the lengths and elements are immutable (elements are mutable) and seem to be a more lightweight, secure list.
Dictionary dict: Key-value pairs structure hash table, as the nature of hash table, key unordered and not repeat, adding and removing changes conv

You can use the base parameter to change the base of the logarithm. such as Math.log (100,base=10) math.sqrt (x) # square-Root trigonometric functions: Math.sin (x), Math.Cos (x), Math.tan (x), Math.asin (x), Math.acos (x) , Math.atan (x)
These functions receive an X in radians (radian) as a parameter.

Back to top of 1. IteratorsIterators are a way to access the elements of a collection. An iterator object is accessed from the first element of the collection, knowing that all of the elements have been accessed and finished. Iterators can only move forward witho

This article describes the Python collection types (listtupledictsetgenerator). The collection types embedded in Python include list, tuple, set, and dict.
List: a list that looks like an array, but is more powerful than an array. it supports indexing, slicing, searching, and addition.
Tuple: the tuple function is similar to the list function. However, once generated, the length and elements are immutable

of the lightweight threading I've described in this column is a little different from the meaning of OS threads. As far as this is concerned, they are not the same as those provided by Stackless. In many ways, lightweight threads are much simpler than most variants; most of the questions about signals, locks, and the like don't exist. The price of simplicity is that I propose a form of "collaborative multithreading"; I think it's not feasible to add preemption to the standard

Math.pow (x,y) # exponential operation, get x y-square
Math.log (x) # logarithm, the default base is E. You can use the base parameter to change the bases of the logarithm. Like Math.log (100,base=10)
MATH.SQRT (x) # square root
Trigonometric functions: Math.sin (x), Math.Cos (x), Math.tan (x), Math.asin (x), Math.acos (x), Math.atan (x)
These functions receive an X in radians (radian) as an argument.
