多维数组中int的加法

Question

我真的很傻，但是如何找到数组的元素并添加一个元素呢？问题是将项目和数量添加到购物车中。所以我需要在数量上添加一个，这是第二个输入。即多数组将包含[item] [quantity]

else:
    print ("That item is already in your cart")
    add = input("Want to add one more to your cart?")
    if add == "yes":
        addItem(strChoice)



def addItem(strChoice):
    #TO DO
    #Find the strChoice in the aryCart and then add one to the qty 
    for i in strChoice:
      aryCart = [strChoice][i+1]

Answer 1

一些注意事项：是的，您需要提供额外的代码，这是一个示例。aryCart必须是字典，而不是数组。下面是一个示例，它是如何完成的。

aryCart = {'a':1,'b':2,'c':2}
print(aryCart)
def addItem(strChoice):
    #TO DO
    #Find the strChoice in the aryCart and then add one to the qty 
    for i in aryCart:
        if(i == strChoice):
            aryCart[i] = aryCart[i]+1

print ("That item is already in your cart")
add = input("Want to add one more to your cart?")
strChoice = input()
if add == "yes":
    addItem(strChoice)  # Whatever your strChoice is 

print(aryCart)
