first, the meaning of the moduleIn the development of computer programs, as the program code more and more, in a file code will be more and more long, more and more difficult to maintain.In order to write maintainable code, we grouped many functions into separate files so that each file contained relatively few code, and many programming languages used this way of organizing code. In Python, a. py file is called a

Using the urllib or urllib2 module that comes with Pyhton to capture webpages may be a bit lazy. Let's take a look at some new things today. Let's take a look at the tutorial of using the lxml module and the Requests module to capture HTML pages in Python: Web captureThe Web site uses HTML description, which means that

' )print md5.hexdigest ()MD5 is the most common digest algorithm and is fast enough to generate a fixed byte of bytes, typically represented by a 32-bit 16 binary string. Another common digest algorithm is SHA1, which calls SHA1 and calls MD5 ex

"Import Module" Unlike the # include in C, the import statement in Python does not simply insert a file into another file.Import is actually run-time operations, the first time the program imports the specified file, the following steps are performed, 1.
