python - “type”对象不可下标

Question

import pandas as pd
import numpy as np

fruits = ["APPLE","BANANA","GRAPES","ORANGE"]
prices = [80,45,60,50]


fru_prices = pd.DataFrame[fruits,prices]

I am getting error while I am creating a Data Frame : 'type' object is not subscriptable

Answer 1

您必须调用DataFrame，然后作为参数执行列表:

fru_prices=pd.DataFrame([fruits,prices])

正如你想要转置的那样:

fru_prices=fru_prices.T

并且需要列:

fru_prices.columns=['fruits','prices']

那么fru_prices就是你想要的

实际上你可以在一行中完成这一切:

fru_prices=pd.DataFrame([fruits,prices],index=['fruit','prices']).T
