Python 文件操作之Copy

本文主要是介绍Python 文件操作之Copy，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

用到的知识点：

类的继承

open(read,write,close)

readline

with open as f 迭代器，自动关闭文件，内存清理

class FileOperation(object):def __init__(self):print('Start Operate File...')def Copy(self,src,dst):print('srouce file location = ',src)print('dest file location = ',dst)try:file_src = open(src)file_dst = open(dst,"w")while(True):line_src = file_src.readline()file_dst.write(line_src)if not line_src:breakexcept:print('------------------>Check File if exist!<---------------------')  finally:file_src.close()file_dst.close()print('Done File Copy...')class File(FileOperation):def __init__(self):print('Start WithCopy File...')def WithCopy(self,src,dst):try:with open(src,'r') as file_src:with open(dst,'w') as file_dst:for line in file_src:file_dst.write(line)except:print('WithCopy Failed!')finally:print('Done WithCopy File!')if __name__ == '__main__':Op_File = File()Op_File.Copy('/var/www/Python/FileOp/test.py','/var/www/Python/FileOp/copy.py')Op_File.WithCopy('/var/www/Python/FileOp/test.py','/var/www/Python/FileOp/withcopy.py')
