用python查找指定格式或名称的文件及修改指定文件夹名称

写这个也是为了能更好的学习python，大家有什么意见可以提出来，这个代码直接放到编译器中运行即可。

import os, sys, re

newdir = ""

#递归搜索函数
def search(rootdir,searchdirname):
        if os.path.isdir(rootdir):
                #print rootdir
                #分离路径和文件夹
                split1 = os.path.split(rootdir)
                #print split1[1]

                #判断是否为指定的文件夹
                if split1[1] == searchdirname:
                        print "找到文件夹：%s" % (rootdir)
                        try:
                                #将文件夹名称改为新的文件夹名称
                                os.rename(rootdir,split1[0]+"\\"+newdir)
                                print "文件夹 [%s] 已改名为 [%s]" % (rootdir,newdir)
                        except:
                                pass

                #遍历指定文件夹下的内容（文件和文件夹列表）
                listnew = os.listdir(rootdir)

                for l1 in listnew:
                        path = rootdir + "\\" + l1
                        #递归调用
                        search(path,searchdirname)
        else:
                #print '不是文件夹：%s' % (rootdir)
                return
        
#搜索指定格式的文件        
def find_file_by_pattern(pattern,base):        
        '''''查找给定文件夹下面所有 '''    
        re_file = re.compile(pattern)        
        if base == ".":        
                base = os.getcwd()        
                        
        final_file_list = []        
        #print base        
        cur_list = os.listdir(base)        
        for item in cur_list:        
                print item
                full_path = os.path.join(base, item)        
                if full_path.endswith(pattern):#不能写成单引号，单引号达不到预期的效果
                # print full_path        
                        #bfile = os.path.isfile(item)
                        if os.path.isfile(full_path):
                             if re_file.search(full_path):
                                     print re_file.search(full_path).group()
                                     final_file_list.append(full_path)        
                        else:        
                             final_file_list += find_file_by_pattern(pattern,full_path)
                #for filename in re_file.findall(final_file_list):
                     # print filename
                else:
                        continue
        return final_file_list

def serchDir(startdir,dirname):
        search(startdir,dirname)
        
if __name__ == '__main__':
        root=raw_input("输入搜索目录:")
        key=raw_input("输入待搜索的文件夹名称:")
        #newdir = raw_input("文件夹改名为：")
        #serchDir(root,key)
        base="".join([root,key])
        fileName=raw_input("请输入要查找的文件名称或后缀名:")
        for result in find_file_by_pattern(fileName,base):
                print result

如果要查找指定名字的文件只需要将以下代码屏幕即可

if full_path.endswith(pattern):#不能写成单引号，单引号达不到预期的效果
......
......
......
else:
                        continue

将这三行屏幕后就可以用文件名进行搜索了。
