TypeError：'int'对象不支持项目分配Python

Posted 2021-04-08

[谁能告诉我为什么我在Python 2.7中不断收到此错误，请参见下面的错误标记。预先感谢！

我必须编写一个程序来计算每人的硬币数量并弄清它们的总数

TotalPeople = int(raw_input("Enter the number of people "))
Loop = 0
DC2 = 0
DC1 = 0
C50 = 0
C25 = 0 
C10 = 0
C5 = 0 
C2 = 0 
TVC = 0.0
i = 1

while i != TotalPeople:
    DC2[i] = raw_input("How many 2 dollar coins?")     // ERROR for this line
    DC1[i] = raw_input("How many 1 dollar coins?")
    C50[i] = raw_input("How many 50 cent coins?")
    C25[i] = raw_input("How many 25 cent coins?")
    C10[i] = raw_input("How many 10 cent coins?")
    C5[i] = raw_input("How many 5 cent coins?")
    C2[i] = raw_input("How many 2 cent coins?")
    Total =  (DC2[i] *2) + (DC1[i] * 1) + (C50[i] * 0.50) + (C25[i] * 0.25) + (C10[i] * 0.10) + (C5[i] * 0.05) + (C2[i] * 0.02)
    print "The total is " + Total

iw = 1
while iw != TotalPeople:
    TVC = TVC + (DC2[iw] * 2)
    TVC = TVC + (DC1[iw] * 1) 
    TVC = TVC + (C50[iw] * 0.50) 
    TVC = TVC + (C25[iw] * 0.25) 
    TVC = TVC + (C10[iw] * 0.10) 
    TVC = TVC + (C5[iw] *  0.05) 
    TVC = TVC + (C2[iw] * 0.02)

print("The total value is CAD $" + str(TVC) + " for " + str(TotalPeople) +  " people") 

答案

您已将DC声明为整数，但在此行中：

DC2[i] = raw_input("How many 2 dollar coins?")

（以及前面所有连续的行），您正在处理它，就好像它是可定标对象一样。我认为您想要的是摆脱while循环内正在执行的所有索引分配。

DC2 = raw_input("How many 2 dollar coins?") 
DC1 = raw_input("How many 1 dollar coins?")
C50 = raw_input("How many 50 cent coins?")
C25 = raw_input("How many 25 cent coins?")
C10 = raw_input("How many 10 cent coins?")
C5 = raw_input("How many 5 cent coins?")
C2 = raw_input("How many 2 cent coins?")

另一答案

DC2是整数。您正在尝试为其分配它，就像它是list（带有索引）一样。那是行不通的。
