Python复制文件操作实例详解
本文实例讲述了Python复制文件操作用法。分享给大家供大家参考，具体如下：
这里用python实现了一个小型的自动发版本的工具。这个“自动发版本”有点虚， 只是简单地把debug 目录下的配置文件复制到指定目录，把Release下的生成文件复制到同一指定，过滤掉不需要的文件夹(.svn)，然后再往这个指定目录添加几个特定的文件。
这个是我的第一个python小程序。
下面就来看其代码的实现。
首先插入必要的库：
import os import os.path import shutil import time, datetime
然后就是一大堆功能函数。第一个就是把某一目录下的所有文件复制到指定目录中：
def copyFiles(sourceDir, targetDir):
if sourceDir.find(".svn") > 0:
return
for file in os.listdir(sourceDir):
sourceFile = os.path.join(sourceDir, file)
targetFile = os.path.join(targetDir, file)
if os.path.isfile(sourceFile):
if not os.path.exists(targetDir):
os.makedirs(targetDir)
if not os.path.exists(targetFile) or(os.path.exists(targetFile) and (os.path.getsize(targetFile) != os.path.getsize(sourceFile))):
open(targetFile, "wb").write(open(sourceFile, "rb").read())
if os.path.isdir(sourceFile):
First_Directory = False
copyFiles(sourceFile, targetFile)
删除一级目录下的所有文件：
def removeFileInFirstDir(targetDir):
for file in os.listdir(targetDir):
targetFile = os.path.join(targetDir, file)
if os.path.isfile(targetFile):
os.remove(targetFile)
复制一级目录下的所有文件到指定目录：
def coverFiles(sourceDir, targetDir):
for file in os.listdir(sourceDir):
sourceFile = os.path.join(sourceDir, file)
targetFile = os.path.join(targetDir, file)
#cover the files
if os.path.isfile(sourceFile):
open(targetFile, "wb").write(open(sourceFile, "rb").read())
复制指定文件到目录：
def moveFileto(sourceDir, targetDir): shutil.copy(sourceDir, targetDir)
往指定目录写文本文件：
def writeVersionInfo(targetDir):
open(targetDir, "wb").write("Revison:")
返回当前的日期，以便在创建指定目录的时候用：
def getCurTime():
nowTime = time.localtime()
year = str(nowTime.tm_year)
month = str(nowTime.tm_mon)
if len(month) < 2:
month = '0' + month
day = str(nowTime.tm_yday)
if len(day) < 2:
day = '0' + day
return (year + '-' + month + '-' + day)
然后就是主函数的实现了：
if __name__ =="__main__":
print "Start(S) or Quilt(Q) \n"
flag = True
while (flag):
answer = raw_input()
if 'Q' == answer:
flag = False
elif 'S'== answer :
formatTime = getCurTime()
targetFoldername = "Build " + formatTime + "-01"
Target_File_Path += targetFoldername
copyFiles(Debug_File_Path, Target_File_Path)
removeFileInFirstDir(Target_File_Path)
coverFiles(Release_File_Path, Target_File_Path)
moveFileto(Firebird_File_Path, Target_File_Path)
moveFileto(AssistantGui_File_Path, Target_File_Path)
writeVersionInfo(Target_File_Path+"\\ReadMe.txt")
print "all sucess"
else:
print "not the correct command"
希望本文所述对大家python程序设计有所帮助。

How to beautify the XML format
Apr 02, 2025 pm 09:57 PM
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.
How to open xml format
Apr 02, 2025 pm 09:00 PM
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.
Does XML modification require programming?
Apr 02, 2025 pm 06:51 PM
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.
Is there any mobile app that can convert XML into PDF?
Apr 02, 2025 pm 08:54 PM
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.
Is there a free XML to PDF tool for mobile phones?
Apr 02, 2025 pm 09:12 PM
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.
Is the conversion speed fast when converting XML to PDF on mobile phone?
Apr 02, 2025 pm 10:09 PM
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.
How to convert XML files to PDF on your phone?
Apr 02, 2025 pm 10:12 PM
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.
How to convert XML to PDF on your phone?
Apr 02, 2025 pm 10:18 PM
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.
