Python實現比較兩個檔案夾中代碼變化的方法

本文執行個體講述了Python實現比較兩個檔案夾中代碼變化的方法。分享給大家供大家參考。具體如下：

這裡將修改代碼後的目錄與原始目錄做對比，羅列出新增的代碼檔案，以及修改過的代碼檔案

# -*- coding: utf-8 -*-import os;folderA = "F:\\Projects\\FreeImageV3_14_1\\".lower();folderB = u"E:\\Software\\映像解碼庫\\FreeImage3141\\FreeImage\\".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中不一致的檔案的路徑    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();

希望本文所述對大家的Python程式設計有所協助。
