We often want to count the number of lines of code in a project, but if we want to have a more complete statistical function, it may not be that simple. Today we will take a look at how to use python to implement a line of code statistics tool.
Idea: First get all files, then count the number of lines of code in each file, and finally add the number of lines.
Function implemented:
Count each The number of lines in the file;
Statistics the total number of lines;
Statistics running time;
Supports specifying statistical file types and excludes file types that do not want to be counted;
Recursion Count the number of lines of files in the folder including sub-files;
Exclude empty lines;
# coding=utf-8 import os import time basedir = '/root/script' filelists = [] # 指定想要统计的文件类型 whitelist = ['php', 'py'] #遍历文件, 递归遍历文件夹中的所有 def getFile(basedir): global filelists for parent,dirnames,filenames in os.walk(basedir): #for dirname in dirnames: # getFile(os.path.join(parent,dirname)) #递归 for filename in filenames: ext = filename.split('.')[-1] #只统计指定的文件类型,略过一些log和cache文件 if ext in whitelist: filelists.append(os.path.join(parent,filename)) #统计一个文件的行数 def countLine(fname): count = 0 for file_line in open(fname).xreadlines(): if file_line != '' and file_line != '\n': #过滤掉空行 count += 1 print fname + '----' , count return count if name == 'main' : startTime = time.clock() getFile(basedir) totalline = 0 for filelist in filelists: totalline = totalline + countLine(filelist) print 'total lines:',totalline print 'Done! Cost Time: %0.2f second' % (time.clock() - startTime)
Result:
[root@pythontab script]# python countCodeLine.py /root/script/test/gametest.php---- 16 /root/script/smtp.php---- 284 /root/script/gametest.php---- 16 /root/script/countCodeLine.py---- 33 /root/script/sendmail.php---- 17 /root/script/test/gametest.php---- 16 total lines: 382 Done! Cost Time: 0.00 second [root@pythontab script]#
Only It is very convenient to count php and python files.
In fact, you can also make improvements on this basis, such as excluding comment lines, etc.

XML beautification is essentially improving its readability, including reasonable indentation, line breaks and tag organization. The principle is to traverse the XML tree, add indentation according to the level, and handle empty tags and tags containing text. Python's xml.etree.ElementTree library provides a convenient pretty_xml() function that can implement the above beautification process.

Use most text editors to open XML files; if you need a more intuitive tree display, you can use an XML editor, such as Oxygen XML Editor or XMLSpy; if you process XML data in a program, you need to use a programming language (such as Python) and XML libraries (such as xml.etree.ElementTree) to parse.

Modifying XML content requires programming, because it requires accurate finding of the target nodes to add, delete, modify and check. The programming language has corresponding libraries to process XML and provides APIs to perform safe, efficient and controllable operations like operating databases.

An application that converts XML directly to PDF cannot be found because they are two fundamentally different formats. XML is used to store data, while PDF is used to display documents. To complete the transformation, you can use programming languages and libraries such as Python and ReportLab to parse XML data and generate PDF documents.

There is no simple and direct free XML to PDF tool on mobile. The required data visualization process involves complex data understanding and rendering, and most of the so-called "free" tools on the market have poor experience. It is recommended to use computer-side tools or use cloud services, or develop apps yourself to obtain more reliable conversion effects.

The speed of mobile XML to PDF depends on the following factors: the complexity of XML structure. Mobile hardware configuration conversion method (library, algorithm) code quality optimization methods (select efficient libraries, optimize algorithms, cache data, and utilize multi-threading). Overall, there is no absolute answer and it needs to be optimized according to the specific situation.

It is impossible to complete XML to PDF conversion directly on your phone with a single application. It is necessary to use cloud services, which can be achieved through two steps: 1. Convert XML to PDF in the cloud, 2. Access or download the converted PDF file on the mobile phone.

It is not easy to convert XML to PDF directly on your phone, but it can be achieved with the help of cloud services. It is recommended to use a lightweight mobile app to upload XML files and receive generated PDFs, and convert them with cloud APIs. Cloud APIs use serverless computing services, and choosing the right platform is crucial. Complexity, error handling, security, and optimization strategies need to be considered when handling XML parsing and PDF generation. The entire process requires the front-end app and the back-end API to work together, and it requires some understanding of a variety of technologies.
