我的Python代码出了什么问题？

Question

我正在为我的计算机编程原理介绍课做最后一个项目，我从一个旧的项目中找到一个项目的价格，并转换成显示一个NFL团队的最终分数。在

我的第一个有效代码：

#Start Program

foundItemFlag = False
itemNum = (34, 124, 178, 219, 225) 
price = (3.76, 1.29, 4.78, 2.76, 4.51) 
input = int(input("Enter the Item Number: "))
for k in range (5):
    if input == itemNum[k]:
        foundItemFlag = True
        print("The item number you've chosen is ", input, "and the price is ", price[k])
if (foundItemFlag == False):
    print("Invalid Item Number!")

#End Program

这是我转换后的代码，我正试图修复。。在

^{pr2}$

我是一个初学者，把我的代码复制到IDLE中，收到了NFL代码的以下错误：

SyntaxError: multiple statements found while compiling a single statement

你在混合数据类型。例如，final元组中有数字和字符串。另外，在读取输入时，您需要一个团队名称，这是一个字符串，但将其转换为int。首先，试试这个：

foundTeamFlag = False
teamName = ("Bills", "Dolphins", "Patriots", "Jets", "Ravens", "Bengals", "Browns", "Steelers", "Texans", "Colts", "Jaguars", "Titans", "Broncos", "Chiefs", "Raiders", "Chargers")
final = ("6-10", "7-9", "12-4", "6-10", "10-6", "10-6", "5-11", "8-8", "12-4", "11-5", "2-14", "6-10", "13-3", "2-14", "4-12", "7-9")
inp = raw_input("To find your team's final record for last season please type in their name (Ravens, Texans and etc) : ")

for k in range(5):
    if inp == teamName[k]:
        foundTeamFlag = True
        print("The ", inp, "final record for 2012-2013 was ", final[k])
        break

if foundTeamFlag == False:
    print("Oops, check your team name and try again!")

现在，要想找到一种更具Python式的方法来解决这个问题，请抛弃循环，使用类似这样的字典：

^{pr2}$

我假设您使用的是python3.X？以下是你做错的事情：

1. 将用户的输入（字符串）转换为int：这行不通
2. 将内置“input”重新指派给变量名
3. 只迭代变量“final”的前5个元素
4. 正如另一个答案者指出的，您可能希望在“final”元组中使用字符串

我将执行以下操作（对于python3.x，将raw_input替换为input）：

foundTeamFlag = False
teamName = ("Bills", "Dolphins", "Patriots", "Jets", "Ravens", "Bengals", "Browns", "Steelers", "Texans", "Colts", "Jaguars", "Titans", "Broncos", "Chiefs", "Raiders", "Chargers") 
finalScores = ("6-10", "7-9", "12-4", "6-10", "10-6", "10-6", "5-11", "8-8", "12-4", "11-5", "2-14", "6-10", "13-3", "2-14", "4-12", "7-9") 
userInput = raw_input("To find your team's final record for last season please type in their name (Ravens, Texans and etc) :")
for name, score in zip(teamName, finalScores):
    if userInput == name:
        foundTeamFlag = True
        print("The ", userInput, "final record for 2012-2013 was ", score)
        break
if (foundTeamFlag == False):
    print("Oops, check your team name and try again!")

Answer 3

你对final的定义有一个问题：

final = (6-10, 7-9, "12-4", "6-10", "10-6", "10-6", "5-11", "8-8", "12-4", "11-5", "2-14", "6-10", "13-3", "2-14", "4-12", "7-9")

这里有减法语句（前2个）。将它们改为字符串：

^{pr2}$

另外，不要使用input、list、pass等名称作为变量名。。。在

正如评论人士指出的，这不是主要原因

• 您要求用户输入团队名称，但将其转换为整数。。在
• 您只迭代元组的前5个元素。。。在

您的最终代码应该是：

foundTeamFlag = False
teamName = ("Bills", "Dolphins", "Patriots", "Jets", "Ravens", "Bengals", "Browns", "Steelers", "Texans", "Colts", "Jaguars", "Titans", "Broncos", "Chiefs", "Raiders", "Chargers") 
teams = ("6-10", "7-9", "12-4", "6-10", "10-6", "10-6", "5-11", "8-8", "12-4", "11-5", "2-14", "6-10", "13-3", "2-14", "4-12", "7-9") 
inp = input("To find your team's final record for last season please type in their name (Ravens, Texans and etc) : ")
for k in range(len(teams)):
    if inp == teamName[k]:
        foundTeamFlag = True
        print("The ", input, "final record for 2012-2013 was ", teams[k])
if (foundTeamFlag == False):
    print("Oops, check your team name and try again!")

但更灵活的方法是使用字典：

^{4}$
