python遍歷文件夾是兩種方式：
# -*- coding: utf-8 -*-
import os
def Test1(rootDir):
list_dirs = os.walk(rootDir)
for root, dirs, files in list_dirs:
for d in dirs:
print os.path.join(root, d)
for f in files:
print os.path.join(root, f)
# -*- coding: utf-8 -*-
import os
def Test2(rootDir):
for lists in os.listdir(rootDir):
path = os.path.join(rootDir, lists)
print path
if os.path.isdir(path):
Test2(path)
第一種是先輸出當(dāng)前目錄下的所有的文件和文件夾，是一層層向下的，而第二種是每個(gè)樹(shù)遍歷完了在遍歷新的一個(gè)父節(jié)點(diǎn)的，類(lèi)似先序遍歷
這里選擇第一種方式加以修改，生成所需的json文件

while(fnum > 0):
