代码如下：

import urllib.request
import pandas as pd
import os

data = pd.read_csv('/Users/xuqiong/AgeGender/Img/DiF/DiF_v1_tiny.csv')
#print(data.head())

#print(data.iloc[0])
print(data.shape[0])

for i in range(data.shape[0]):
    id1, pic = data.iloc[i]
    f = urllib.request.urlopen(pic)
    da = f.read()
    with open('./pic/{0}.jpg'.format(id1), 'wb') as code:
        code.write(da)

    if i % 100 == 0:
        print(i)
