在真偽陳述句中使用來自兩個單獨函式的兩個變數而沒有錯誤來創建字典

編碼：

def NUMBER(i):
    i = input("enter code: ")
    minimum = 0
    maxiumum = 39 
    if i == "END":
        return False
    elif int(i) > minimum and int(i) <= maximum:
        return i
        return True
    else:
        return False
   
    
def AMOUNT(q):
    q = input("enter quantity: ")
    minimum = 0
    maxiumum = 49
    if int(q) > minimum and int(q):
        return True
    else:
        return False
    

number_result = NUMBER(i)
amount_result = AMOUNT(q)        
    
def shop(i, q):
    number_input = []
    amount_inputed = []
    NUMBER()
    AMOUNT()
    while True:    
        if i != "END":
            if number_result == True and amount_result == True:
                number_input.append(int(i))
                amount_inputed.append(int(q))
            elif number_result == True and amount_result == False:
                print("Invalid Quanity")
                break
            elif number_result == False and amount_result == True:
                print ("Invalid code")
                break 
            else:
                print("Invalid inputs")
                break 
    return number_input,amount_inputed
        

def showRecord(number_input, amount_inputed):
    product_info = {}
    for kk in range(len(number_input)):
        quan = amount_inputed[kk]
        kk = number_input[kk]
        price = priceList[kk] 
        total_price = priceList[kk] * quan
        product = productList[kk]
        if kk not in product_info:
            product_info[kk] = [kk, quan, price, product]
        else:
            product_info[kk][1]  = quan
            product_info[kk][2] = product_info[kk][1] * price
            sum_amount  = product_info[kk]
            print(sum_amount)
    for x in ["Code", "Quanity", "Price", "Product"]:
        print(x, end="  ")
    print()
    for x in product_info:
        for info in product_info[x]:
            print(info, end="     ")
        print()
    

number_input,amount_inputed= shop(i,q)
showRecord(cod1e,code2)


shop(NUMBER(i), AMOUNT(q))

您好，我正在嘗試跨兩個單獨的函式（NUMBER 和 AMOUNT）為值 i 和 q 創建一個驗證系統。我希望函式運行 NUMBER 和 AMOUNT，如果輸入的數字有效，則繼續重復回圈，直到 i 為“END”或小于 0/大于 39。對于小于 0 的 q 大于 49。

一旦eithier/both都是False或輸入END，我想收集輸入的值并運行shop（）。

我嘗試了 i 和 q 的兩個全域變數，但它沒有作業，并在它們的每個函式中定義 i 和 q 但發生了同樣的錯誤。

檔案“/Users/stev/Documents/shopping_cart.py”，第 57 行，在 number_result = NUM??BER(i) NameError: name 'i' is not defined。你的意思是：'id'？

我不知道要添加什么代碼，所以我添加了所有內容（如果不允許則洗掉我不知道需要什么代碼）。

uj5u.com熱心網友回復：

我剛剛修改了您自己的代碼以使其正常作業。雖然它可以完全改變。

def NUMBER():
    i = input("enter code: ")
    minimum = 0
    maximum = 39 
    
    if (i=="END") or (int(i) > minimum and int(i) <= maximum) :
        return i
    else:
        return False
   
    
def AMOUNT():
    q = input("enter quantity: ")
    minimum = 0
    maximum = 49
    if (int(q) > minimum) and (int(q)<maximum):
        return q
    else:
        return False
    
   
def shop():
    number_input = []
    amount_inputed = []
    
    while True:
        number_result = NUMBER()
        amount_result = AMOUNT()
       
        if number_result=="END":
            print("Canceled by user")
            break
        elif number_result and not(amount_result):
            print("Invalid Quanity")
            break
        elif not(number_result) and amount_result:
            print ("Invalid code")
            break 
        elif not(number_result) and not(amount_result):
            print("invalid input")
            break
        else:
            number_input.append(int(number_result))
            amount_inputed.append(int(amount_result))
    return number_input,amount_inputed
        

number_input,amount_inputed= shop()
print("number_input:",number_input," amount inputed:",amount_inputed)

玩得開心 ：）
