Because the article "http://www.3lian.com/edu/2011/12-03/17078.htmlwww.3lian.com/edu/2011/12-03/17078.html" a lot of people think Tencent complaint is a world-class advanced, And let me come up with a user's account to retrieve the function. Originally do not want to write, because we look at other systems on the line, but, it is obvious that some people are very lazy, do not think, and will not observe, so
We often read some resource files in the code (compared to slices, music, text, etc.). These simple processes are of course not problematic when running alone. However, if we make the code into a jar package, even if the resource files are packaged together, these things will not be found. Take a look at the following code://Source code 1: PackageEdu.hxraid;ImportJava.io.*; Public classResource { Public voidGetResource ()throwsioexception{File File=NewFile ("Bin/resource/res.txt"); BufferedRead

When you select a database, you can use the following statement:
$mongo = new MONGO ("Mongodb://127.0.0.1:27017/admin:admin");
$db = $mongo->dbname.
This time there is a problem, in general, this type of writing can get the database, but if the name of the database has special characters, for example, the database name is: Edu-dashi, th
cheaters can not control the sort basis, that is, outside the site to find the basis for sorting. Then, there is a PageRank analysis, there is a large. The principle of the hyper-chain analysis is to look at the similar links between the Web pages as an important basis, and then, according to the weight of each site to comprehensive analysis. In this way, gov (government websites) and Edu (education websites) are often given higher rankings, and the
separated, and the empty string is automatically ignored as follows:
>>> s= ' love \n\t\r \t\r\n python \n\t\r '>>> S.split ()[' Love ', ' python ']
>>> s= ' www.pku.edu.cn '>>> s.split () #默认空格作为分隔符, but there are no delimiters in the string, so take the entire string as an element of the list[' www.pku.edu.cn ']
>>> s.split ('. ') #以 '. ' As a delimiter, there are no separate times, and how many '. ' Are separated[' www ', ' pku ', ' edu ', ' CN '
The recent study of Python's regular expressions requires batch generation of random data. This involves to the module SYS, time in the Maxint, CTime, the code in the run CTime format times has been the error can not run.
After studying the relevant data, it is found that the Maxint value is different in the operating system, the MAXINT>2^32 is under the 64-bit operating system, and the number of seconds in the 32-bit operating system Maxint=2^32,ctime function is 0~2^32.
