文件、文件夾的處理使用 python

1. 子文件夾的獲取

2. 文件的複製移動

# -*- coding:utf-8 -*-
import os
from shutil import copy2

allDir="D:\\pics\\易烊千璽"
trainDir = "C:\\Users\\WEIJIE\\Desktop\\train_data\\0"


dir=os.listdir(allDir)  #獲取所有子文件夾
index=0

for i in dir:
    folder=os.path.join(allDir, i)
    #trainfolder=os.path.join(trainDir, i)

    trainfiles = os.listdir(folder)
    num_train = len(trainfiles)
    print("num_train: " + str(num_train))
    index_list = list(range(num_train))

    for i in index_list:
        fileName = os.path.join(folder, trainfiles[i])
        outfile=os.path.join(trainDir, str(index)+'_'+trainfiles[i])
        copy2(fileName,outfile)   #複製文件
    index+=1
