python批量修改文件名

# 导入os csv模块
import os
import csv
# 文件存放路径
pathPictures = "D:\\test\\pictures"
# names存放路径
pathNames = "D:\\test\\info\\names.csv"
# names存入数组
with open(pathNames,"r",encoding="utf-8") as f:
    reader = csv.reader(f)
    data_as_list = list(reader)
# 遍历文件并修改文件名
empNo = 1
for file in os.listdir(pathPictures):
    newName = (data_as_list[empNo])[0] + (data_as_list[empNo])[1]
    os.rename(os.path.join(pathPictures, file),os.path.join(pathPictures,str(newName)+".PNG"))
    empNo += 1
