TypeError：'float'对象不可订阅 [英] TypeError: 'float' object is not subscriptable

问题描述

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
PriceList[0][1][2][3][4][5][6]=[PizzaChange]  
PriceList[7][8][9][10][11]=[PizzaChange+3]

基本上我有一个输入，用户将数字值（浮点输入）放入，然后它将设置所有这些上述列表索引到那个价值。出于某种原因，我无法设置它们而不提出：

Basically I have an input that a user will put a number values (float input) into, then it will set all of these aforementioned list indexes to that value. For some reason I can't get it to set them without coming up with a:

TypeError: 'float' object is not subscriptable

错误。我做错了什么，或者我只是以错误的方式看待它？

error. Am I doing something wrong or am I just looking at it the wrong way?

推荐答案

PriceList [0 ] 是一个浮点数。 PriceList [0] [1] 正在尝试访问float的第一个元素。相反，做

PriceList[0] is a float. PriceList[0][1] is trying to access the first element of a float. Instead, do

PriceList[0] = PriceList[1] = ...code omitted... = PriceList[6] = PizzaChange

或

PriceList[0:7] = [PizzaChange]*7
