DemandRecently doing a feature that uses Python to crawl Web pages and then save to local. One of the difficulties encountered is to determine how the page is encoded. There are problems on Baidu, at that time I did not expect to solve their own. 100 degrees found a plug-in called Chardet. Overjoyed, the test is OK. Well, it looks like the problem is solved, butKengFor Mao my request slowed a lot, at first I thought it was python slow, then a check to know, chardet this thing will seriously affe
a linked list and find the start node of the ring?On the Internet to see a solution: Set two pointers fast and slow, the initial values are pointing to the head, slow each time before further, fast each step forward two steps, if the linked list exists ring, then fast must first enter the ring, and slow after entering the ring, two pointers must meet. (Of course, fast head to tail is null, then a chain-free list), so you can determine whether two linked lists Intersect, the program is as follow

, the target point is U, then for any one not selected X (x! = v x! = u) Have dis[v][x] + dis[x][u] > Dis[v][u], if according to such a point of the solution must be able to calculate the positive solution, but the complexity is too high. Using an approximate optimization is to select the closest to the current point of the non-selected points, if there are more than one of the same distance, select the BFS in turn. This total complexity is still high, so limit the number of searches, the final

What is the use of variables? Wow, that's very useful. the simplest is that you cannot determine the value of the variable when the program is running. For example, in the program we compiled in the previous lesson, you cannot determine what InputBox returns (remember the return value of Inputbox? Is the content you entered), so you cannot cope with various situations, but we use the name "box" to pack the
log processing methods, they are directly included in the logging module, while other methods are included in the logging. handlers module,For more information about how to use the above processing methods, see python2.5 manual.

In Python, you use the Str object to save the string. The Str object is simple to build, using either single or double quotes or 3 single quotes. For example:
S= ' Nice ' #output: NiceS= ' Nice ' #output: NiceS= "Let ' s Go" #output: Let's GoS= ' Nice ' #output: "Nice"S=STR (1) #output: 1s= ' ' NiceDay "' #output: Nice#output: Day

First of all, discuss a simple and straightforward question, why learn multithreading? So the reason is very simple, will be multi-threading, you will be able to raise wages or find a better job Ah!!!A joke.Well, it's not really funny.What problems can multithreading solve?For example, there are two tasks, A/b, at the same time, a need to 10s,b 2s. Before there are many threads, the usual practice is nothing more than two, first execute a and then B, or execute B before executing a, the result o
