python - 数据库 及 TypeError: 'zip' object is not subscriptable

import numpy as np

from pandas import Series, DataFrame   # pandas 数据分析包

#使用数据库
import sqlite3

cursor.description

DataFrame(rows, columns=list(zip(*cursor.description))[0])

'''
DataFrame(rows, columns=zip(*cursor.description)[0])
运行报错：TypeError: 'zip' object is not subscriptable
因为 python 3.x 需要 list()后，再索引查找元素
改为 DataFrame(rows, columns=list(zip(*cursor.description))[0])
