'''
1. read the whole files under a certain folder
2. chose 10000 files randomly
3. copy them to another folder and save
'''
import os, random, shutil


def copyFile(fileDir,tarDir):
    # 1
	pathDir = os.listdir(fileDir)

    # 2
	sample = random.sample(pathDir, 10000)
	print sample
	
	# 3
	for name in sample:
		shutil.copyfile(fileDir+name, tarDir+name)
if __name__ == '__main__':
	fileDir = "/home/lys/img_align_celeba_png/"
	tarDir = '/home/lys/celebA/'
	copyFile(fileDir,tarDir)

遇到的問題：

 shell命令行下for循環內部要有四個空格;回車兩次for循環執行;copy文件時，目錄最後要有/，否則直接把文件名字添加在了目錄後面，更改路徑
