Through the TCP/IP protocol learning, I wrote a can achieve the Pcap file in the IPV4 TCP stream extraction, as well as extract the specified TCP stream, in order to learn, did not adopt the third party package parsing pcap, but the analysis of the bytes stream, the core idea is: If you want to extract TCP Content, in the lower-level IPV4 protocol to determine wh

From a simple perspective, the zip format will be a good choice, and Python's support for the ZIP format is simple and easy to use. 1) Simple Application If you only want to use python for compression and decompression, you don't need to repeat the document. Here we provide a simple usage for you to understand at a glance. Import zipfile F = zipfile.zipfile('filename.zip ', 'w', zipfile. zip_deflated) F.write('file1.txt ') F.write('file2.doc ') F.

Python's Tarfile module makes it easy to read tar archive files, and Cow B is able to handle compressed archive files using gzip and bz2 tar.gz and tar.bz2. Corresponding to the Tarfile is the ZipFile module, ZipFile is the processing of zip compression. Note: Os.system (cmd) allows the Python script to execute commands, of course including: Tar-czf *.tar.gz *,tar-xzf *.tar.gz,unzip and so on, when I think this can solve the problem, but I feel very a

Reading floating-point data from a text file is one of the most common tasks, and Python does not have scanf such input functions, but we can use regular expressions to extract floating-point numbers from a read string Copy Code code as follows: Import re fp = open (' C:/1.txt ', ' R ') s = Fp.readline () Print (s) Alist = Re.findall (' [

in the Python help document is that Iteralbe refers to an object that can return one of its members at one time.Iteralbe mainly includes 3 categories:The first class is all sequence types, such as list (lists), STR (strings), tuple (tuples).The second class is a number of dict types, such as a dictionary, file, and so on.The third class is the object of any class you define that contains the __iter__ () or

I have already posted a piece of code about Baidu Post bar grabbing. today, let's take a look at the community version of the code and refer to the idea of grabbing the Encyclopedia of the community, for more information, see Baidu Post Bar's crawler production. it works basically the same as Baibai's crawler production. The key data is deducted from the source code and stored in a local txt file. Project content: Web crawler of Baidu Post Bar writte

Python applets, file operations and other Below are several small programs written by myself for file operations, including file operations and the use of lists (collections and dictionaries. For example, read a row of data from a file, store it in the list, and then perform

These files were previously extracted using a colleague's batch file; Not quite handy, just recently learning some python, all on their own to write a Python extract files applet; 1. Principle The principle of extracting files is very simple, that is, to a specified directory, to find the last modified time than a gi
