使用os.walk()方法

其中第一个为起始路径，

第二个为起始路径下的文件夹,

第三个是起始路径下的文件.

遍历 D盘sql、zip格式的文件

#coding:utf-8

import os
def main(name,*types):
    for root,dirs,files in os.walk(name):
        for f in files:
            if os.path.isfile(os.path.join(root,f)) and os.path.splitext(f)[1][1:] in types:
                print os.path.join(root,f)

if __name__ == '__main__':
    main(r"D:\\","sql","zip")

与线程一起：

#coding:utf-8
import threading
import os
import time
def main(name,*types):
    for root,dirs,files in os.walk(name):
        for f in files:
            if os.path.isfile(os.path.join(root,f)) and os.path.splitext(f)[1][1:] in types:
                print os.path.join(root,f)

if __name__ == '__main__':

    t1=time.time()
    #加入线程，搜索D盘 以.sql、.zip结尾的文件
    t = threading.Thread(target=main,args=(r"D:\\","sql","zip"))
    t.start()
    t.join()
    #计算执行时间
    print time.time()-t1

# 使用os.walk()方法输出E盘下的mp3文件
import os,re
p = re.compile('.*?\.mp3')
f = os.walk(r'E:\\')  #遍历E盘
result = []
for root,dirs,files in f:
    for m in files:
        if p.search(m):
            print os.path.join(root,m)
            result.append(os.path.join(root,m))

print len(result)

#使用os.walk()
import os

def getfile(path):

    for root,dirs,f in os.walk(path):

        for i in f :
            if i.split('.')[-1] in ('mp3','txt'):
                
                print os.path.join(root,i)

getfile(r"E:\\")

# 使用os.walk()方法输出指定盘符下的mp3文件

import os,re
p = re.compile('.*?\.mp3')


#指定遍历的盘符
disk = ['C:\\','D:\\','E:\\','G:\\']

result = []

def getmp3(): #定义函数
    for d in disk:
        f = os.walk(d)#遍历每个盘符

        for root,dirs,files in f:
            for m in files:
                if p.search(m):
                    print os.path.join(root,m)
                    result.append(os.path.join(root,m))
                    print len(result)


getmp3()

import os
def getmp3(disk):
    for root,dirs,files in os.walk(disk):
        for f in files:
            if os.path.splitext(f)[1][1:]=='mp3':
                print os.path.join(root,f)

if __name__=='__main__':
    import string
    for disk in map(lambda x:x+':\\',string.uppercase[2:6]): #变量盘符：C、D、E
        getmp3(disk)
