python 复制文件

Posted 2023-04-23

练习python，用python复制目录及文件，但是目录一多就出错，而且复制的也不全：

import os
import os.path
import time

dateFormat = time.strftime('%Y%m%d',time.localtime())
targetDir = 'C:/Users/Chaoaicai/Desktop/%s' % dateFormat
os.mkdir(targetDir)
sourceDir = 'D:/test'

try:
def copyFile(sourceDir, targetDir):
dirList = os.listdir(sourceDir)
for fileList in dirList:
os.chdir(sourceDir)
if os.path.isdir(fileList):
sourceDir = os.getcwd()+'/'+fileList
targetDir = targetDir+'/'+os.path.split(sourceDir)[1]
os.mkdir(targetDir)
copyFile(sourceDir, targetDir)
else:
open(targetDir+'/'+fileList,'wb').write(open(sourceDir+'/'+fileList,'rb').read())
except CopyFileError,error:
print ('copyFile error: %s' % error)

copyFile(sourceDir, targetDir)

用Python把某一目录下的文件复制到指定目录中，代码如下：

1、首先插入必要的库：

import os 
import os.path 
import shutil 
import time,  datetime

2、实现复制文件代码如下：

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)

3、主函数的实现：

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" 参考技术A

报错多半是这句 targetDir = targetDir+'/'+os.path.split(sourceDir)[1]

你这句把本来的targetDir覆盖了，导致后面的文件的目标文件夹被修改

发个我写的吧，参考下吧

def copyFile( sourceDir,targetDir ):
    if not os.path.exists( targetDir ):
        os.makedirs( targetDir )
    
    for filename in os.listdir( sourceDir ):
        path = os.path.join( sourceDir,filename )
        if os.path.isdir( path ):
            targetSubDir = os.path.join( targetDir,filename )
            copyFile( path,targetSubDir )
        else:
            targetPath = os.path.join( targetDir,filename )
            open( targetPath,'wb' ).write( open( path,'rb' ).read() )

本回答被提问者采纳 参考技术B 学习自带库, 并学会如何查资料. 然后你就能发现Python是有函数用来实现这种功能

shutil.copytree(src, dst, symlinks=False, ignore=None) 参考技术C windows下你就不要自己用"/"了，还有，哪有这样递归的。。。
