1.檔案移動與複製

# encoding:utf-8
import os
import shutil
shutil.move(os.path.join(path1,pic), os.path.join(dst_path, pic))
shutil.copy(pic1, os.path.join(dst_path, pic1))

2.檔案遍歷

path1="/home/xionglin/274G2/face0413/dataset"
dst_path="/home/xionglin/274G2/face0413/train"

fs1 = os.listdir(path1)
# fs2 = os.listdir(path2)
 


for imagefolder in fs1:
    ……

3.字串比較

if cmp(str1, str2) == 0:

如果兩個字串相等返回0，小於返回-1，大於返回1

4.字串分割

str2=pic2.split("_")[1].split(".")[0]

5.路徑合成

os.path.join(dst_path,imagefolder)
