Python - 批量更改文件名

由于网络云盘对分享视频文件的限制，现在很多视频文件都更改了扩展名。同时网站又喜欢把文件名加上URL进行网站推广，导致下载电视剧后需要大量修改文件名，很麻烦。针对这个问题，用Python写了一个脚本，批量修改，一次搞定。

#coding: utf8import osdef defineRule(old, new, rules):    '''Define single rule: replace old with new       and append the rule to rules(list)    '''       rule = [old, new]    rules.append(rule)  def BatchChangeFileName(folder, rules):    '''    Change file names in folder, according to the rule defined    '''    files = os.listdir(folder)       for file in files:        fullSourceName = os.path.normpath(os.path.join(folder, file))        fullNewName = fullSourceName        for rule in rules:                  fullNewName = fullNewName.replace(rule[0], rule[1])        # only change name when having differences           if not fullSourceName.__eq__(fullNewName):              os.rename(fullSourceName, fullNewName)                    print (fullSourceName, 'is changed to', fullNewName)          #-----------------------------# Test and demo usagerules = []defineRule('[www.xingk.cc 星空家园]', '', rules) defineRule('mkv1.XK.PDF', 'mkv', rules)BatchChangeFileName(r'D:\downloads\芈月传', rules)
