This article mainly introduces how to use the dictionary in Python to process index statistics. the dictionary is used as the basic knowledge in Python learning. This article is a related small practice, for more information about index engines and data statistics, see this article. I have worked with the Python dictionary frequently. now I have compiled a copy of the API usage and archive filing.
The basic working principle of the indexing engine is

cables and high-loss connectors. Optical Time Domain Reflector OTDR) can test the performance of installed optical cables and file their documents for record filing. OTDR displays a graphical curve of an installed optical cable. You can set active pointers on the graphic curve to measure the cable length, distance from the event, and evaluate the power loss between any two points. In addition, OptiFiber can analyze the curve and explain it in the eve
As an evolution after 3G-4G, do you know its technical characteristics? As one of the 4G standard record filing systems, wireless TD-LTE-Advanced adopts the multi-access method, frame structure similar to TD, and wireless MIMO technology. The following is a detailed introduction.
Features of wireless TD-LTE-Advanced Technology
1. Multiple Access Method
The wireless TD-LTE is based on OFDM technology, and OFDMA is used in the downlink. the uplink adopt

An important habit is to install all programs in another partition to reduce the size of the system partition;7. delete records and backups used for system restoration under the root directory of the System Disk-for the XP system, even if the system is just installed, there may also be dozens or even hundreds of MB backup files in the System Volume Information directory (click "Tools> Folder Options> View ", uncheck "H
analyzer based on Window are displayed intuitively and easy to use. It can also reduce training time and improve work efficiency. The tester can set a security level based on the user level and technical level.◎ Powerful Cable Testing Functions The tester automatically performs a cable test and displays the length from the connection location to the connected device, the wiring diagram of the cable, the characteristic impedance, And the length to the endpoint, the length to the reflection point
Hong Kong servers are not subject to record filing restrictions, and there is no problem of interconnection between China Telecom and China Netcom. These advantages allow Hong Kong servers to quickly become "star products" in the eyes of enterprises and webmasters ". Recently, some phenomena have occurred on the Internet. You only need to spend several hundred RMB per month to rent servers in Hong Kong. Customers who have been in contact with regular
How to determine whether a php constant has been defined, suddenly confused, dizzy, specially checked the manual, the record filing summary results are as follows:
(1) determine whether a constant exists
If (defined ('myconstant') {echo MYCONSTANT ;}
(2) determine whether a variable is defined
If (isset ($ myvar) {echo "variable $ myvar .";}
(3) determine whether a function exists
If (function_exists ('imap _ open') {echo "function imag_open";}
options.
2 Linux Firewall intrusion detection extension matching design
Currently, intrusion detection systems generally adopt precise pattern matching algorithms. For example, Snort uses rule-based rules to match data packets to detect a variety of intrusion behaviors and detection activities, this method is simple and effective. Therefore, you can use this method to add matching options to firewall matching options to detect the content in data packets. Because the Extended IP table has go

Summary: network management is full of the crisis caused by illegal use of the network. Therefore, we need to make reasonable planning of the network structure at ordinary times, and keep detailed filing information for network
. What CDN obtains is that your domain name has resolved this IP address, and the service list of your CDN carrier does not exist. It will return 404 to you and fail.Therefore, only one of the primary domain names can be selected as the Varnish reverse object. Fortunately, Gravatar allows direct IP Access, saving a lot of trouble.

the network changes after a period of time, and the troubles will come one after another. Let's take a look at two simple pictures at a glance.
Although at the beginning, we also consciously made the cabling and emissions look elegant and easy to find, but with the increase of the user end and the increase of jumper, the entire situation has changed. Think about the situation. If there is a problem at one end, how to find out, how to locate the problem, and if there is no record
value is set to 99%, and 1% of the remaining space is available.
In the Concurrent cleaning stage, if the user thread needs to use more than 1% space, a Concurrent Mode Failure error will be generated, which means that the concurrency Mode fails.
In this case, the virtual machine will start filing: Use the Serial Old collector to re-collect junk data in the Old age. As a result, the pause time becomes longer.

Python: how to disable Function Modification list.
Sometimes, you need to disable the function from modifying the list. For example, to modify the split file, you must keep the original unprinted design list for record filing. To solve this problem, you can pass a copy of the list to the function, instead of the original. In this way, any modification made to the function only affects the copy, without affecting the original.
