[Python] Call the WPS V9 API to convert PPT to PDF and pythonwps. WPS APIs, that is, COM, are mainly divided into V8 and V9 versions. examples that are easy to find on the Internet are V8. You can download the V9 API on the official website. Python needs to install Python for Windows Extensions to call COM, that is,

This example demonstrates Python's method of producing PDF files, which is a more practical function, consisting mainly of 2 files. The implementation methods are as follows: pdf.py files are as follows: #!/usr/bin/python from reportlab.pdfgen import canvas def hello (): c = Canvas. Canvas ("Helloworld.pdf") c.drawstring (100,100, "Hello,world") c.showpage () c.save () Hello ()

This example demonstrates how Python generates PDF files and is a useful feature that consists of 2 files. The implementation method is as follows: The pdf.py file is as follows: #!/usr/bin/pythonfrom reportlab.pdfgen Import Canvasdef hello (): c = Canvas. Canvas ("Helloworld.pdf") c.drawstring (100,100, "Hello,world") c.showpage () c.save () Hello () The diskreport.py file is as follows: #!/u

Python memory management method and garbage collection algorithm parsing, python garbage collection Summary There is a circular reference problem in the list, tuples, instances, classes, dictionaries, and functions. Instances with the _ del _ method will be processed in a sound way. It is easy to add GC support for new types.

Extended Python module series (3) ---- Parameter Parsing and result encapsulation, python ---- In the previous section, we introduced the overall process of extending the Python built-in modules in C language through a simple example. Starting from this section, we will discuss some details in depth, in the detailed di

Example parsing: Python Design Pattern programming: Application of Bridge pattern, python Design Pattern Let's take an example: # Encoding = UTF-8 ## by panda # Bridge Mode def printInfo (info): print unicode (info, 'utf-8 '). encode ('gbk') # Abstract class: mobile phone brand class HandsetBrand (): soft = None def SetHandsetSoft (self, soft): self. soft = soft

,elem.text Since Iterparse is able to scan the elements and get the corresponding text. Then we can convert this function to a builder. The code is modified as follows: defXml_try (Element):Tag_indicate=[]Doc2=iterparse (R ' D:\test_source\rss20.xml ',(' Start ',' End ')) forevent,elem in doc2: if event = = ' start ' : Tag_indicate.append ( Elem.tag) if event = = ' end ' : if tag_indicate.pop () = = element: yield Elem.text __name__==' __main__

Parsing of python tuples and python instances The example in this article describes how to operate python tuples for your reference. The specific analysis is as follows: In general, the usage of python functions is quite flexible, not the same as that of c and php, but quite

Python generator and application instance parsing, python Generator This article focuses on the Python generator and its application, as follows.I. Definition It can be understood as a data type, which automatically implements the iterator protocol (other data types need to call their own built-in _ iter _ method), so

Python command line parsing module details, python command line details This article focuses on the Python command line parsing module. There are two common parser types for Python command lines: getopt module and argparse module.

Source code parsing of a python thread pool, python thread source code Python highly encapsulates many things to facilitate people's programming, such as the process pool in the process, which greatly facilitates the efficiency of People's programming, but there is no thread pool by default, I have sorted out a thread

Python uses lock to access Shared variable instance parsing, python variable This article focuses on the use of lock access Shared variables in python. The specific introduction and implementation are as follows. When multiple threads access a variable at the same time during multi-thread programming in

Python assisted code parsing and python code This Code enables you to manually click the start and end points, and the program automatically determines the distance and touch-screen time to complete the jump. Principles (from the project description page ): 1. Click the cell phone to the "hop-on" applet interface; 2. Use the Adb tool to get the current mobile pho

Python class variable and object variable declaration parsing, python variable Similar to C ++, Python classes also have two types of variables: class variables and object variables! The former is owned by the class and shared by all objects, and the latter is exclusive to each object. Here I mainly want to discuss the

iterators: A preliminary study As mentioned in the previous chapter, a for loop is actually available on any object that can be iterated. In fact, this is true for all of the iterative tools in Python that scan objects from left to right, including for loops, list parsing, in-member relationship testing, and map built-in functions. The concept of an "iterative object" is quite novel in

When you open a. py file, you will often see if __name__ = = ' __main__ ' at the bottom of the code: Now let's introduce its role.The module is an object, and all modules have a built-in property of __name__. The value of the __name__ of a module depends on how you apply the module. If you import a module, the value of the module __name__ is usually the module file name, without the path or file extension. But you can also run the module directly like a standard program, in which case the __name
