Introduction to the method of merging text file contents in Python file operation
众所周知Python文件处理操作方便快捷,下面这篇文章主要给大家介绍了关于Python文件操作之合并文本文件内容的相关资料,文中通过示例代码介绍的非常详细,需要的朋友可以参考借鉴,下面随着小编来一起学习学习吧。
前言
相信大家初入某个项目,一般都要看代码。有时候,想把代码文件打印下来看,不过一般代码文件数量都在两位数或更多,逐一打开、打印,确实太耗费精力了,此外,也会出现某个代码文件打印到纸上只占了一两行的情况,很浪费纸。如果可以合并到一个文本文件里面上面这些问题就解决。
目前一个用的比较多的功能:将多个小文件的内容合并在一个统一的文件中,对原始文件重命名标记其已被处理过。
之前使用其他脚本写的,尝试用python写了一下,顺便熟悉一下python的文件处理命令。
原始文件
经过处理之后
最后还有一个蛋疼的因为缩进产生的第一个回车符
其中包含了文件的创建和移除,文件内容的读写,文件的重命名的语法命令等等
示例代码
# -*- coding: utf-8 -*- import os import time import datetime def merge_file(file_path,file_name): #file_path must exits if(os.path.exists(file_path) is False): print('file_path is not exists') return if(os.path.exists(os.path.join(file_path, file_name))): os.remove(os.path.join(file_path, file_name)) #'%Y_%m_%d%H%M%S',创建一个以日期命名的文本文件 targetfilename = str(time.strftime('%Y%m%d%H%M%S'))+'.txt' fobj = open(os.path.join(file_path, targetfilename), 'w') fobj.close() # a 是以追加的方式打开文件写入 with open(os.path.join(file_path, targetfilename), 'a', encoding='GBK') as f_wirte: files = os.listdir(file_path) for file in files: print(os.path.join(file_path, file)) with open(file_path+'\\'+file, 'r', encoding='GBK') as f: for line in f.readlines(): if(line.strip().__len__()) > 0:# 排除空行 f_wirte.write(line) f_wirte.write('\n')# 每读完一个文件之后,加一个回车,否则第一个文件的最后一行跟第二个文件的第一行没有回车 # 文件合并之后,重命名原始的文件, # os.path.splitext(file)[0] 提取文件名,不包括后缀名 # os.path.splitext(file)[1] 提取文件后缀名 if (file != targetfilename): os.rename(os.path.join(file_path, file),os.path.join(file_path, os.path.splitext(file)[0] + '在_' +str(time.strftime('%Y%m%d%H%M%S')) +'_已处理' + '.txt')) merge_file('D:\TestPythonMergeFile','auoto_create_a_category_file')

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

In VS Code, you can run the program in the terminal through the following steps: Prepare the code and open the integrated terminal to ensure that the code directory is consistent with the terminal working directory. Select the run command according to the programming language (such as Python's python your_file_name.py) to check whether it runs successfully and resolve errors. Use the debugger to improve debugging efficiency.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

VS Code is the full name Visual Studio Code, which is a free and open source cross-platform code editor and development environment developed by Microsoft. It supports a wide range of programming languages and provides syntax highlighting, code automatic completion, code snippets and smart prompts to improve development efficiency. Through a rich extension ecosystem, users can add extensions to specific needs and languages, such as debuggers, code formatting tools, and Git integrations. VS Code also includes an intuitive debugger that helps quickly find and resolve bugs in your code.
