本文实例讲述了Python实现比较两个文件夹中代码变化的方法。分享给大家供大家参考。具体如下：
这里将修改代码后的目录与原始目录做对比，罗列出新增的代码文件，以及修改过的代码文件
# -*- coding: utf-8 -*- import os; folderA = "F:ProjectsFreeImageV3_14_1".lower(); folderB = u"E:Software图像解码库FreeImage3141FreeImage".lower(); filePathsA = {}; filePathsB = {}; for root,dirs,files in os.walk(folderA): for fileName in files: filePathsA[(root + "" + fileName).lower()] = 1; for root,dirs,files in os.walk(folderB): for fileName in files: filePathsB[(root + "" + fileName).lower()] = 1; # 在filePathsA中，找到所有和filePathsB中不一致的文件的路径 modifiedFilePath = []; addedFilePath = []; for filePathA in filePathsA: folderALen = len(folderA); filePathB = folderB + filePathA[folderALen:]; idx = filePathA.rfind("."); if idx == -1: continue; ext = filePathA[idx + 1:]; ext = ext.lower(); if ext != "c" and ext != "h" and ext != "cpp" and ext != "cxx": continue; if filePathB not in filePathsB: addedFilePath.append(filePathA); continue; text_file = open(filePathA, "r"); textA = text_file.read(); text_file.close(); text_file = open(filePathB, "r"); textB = text_file.read(); text_file.close(); if textA != textB: modifiedFilePath.append(filePathA); output = open('res.txt', 'w'); output.write("added files:n"); for filePath in addedFilePath: output.write(filePath + "n"); output.write("modified files:n"); for filePath in modifiedFilePath: output.write(filePath + "n"); output.close();
希望本文所述对大家的Python程序设计有所帮助。
