Python 输入和输出？ [复制]

Question

我正在学习 python，但由于某种原因，我得到的输出总是不正确的。不知道我做错了什么或如何解决它，非常感谢任何帮助：

##a.    3 variables —
##  The name of a movie
##  The number of tickets to purchase
##  The total cost of tickets purchased
##
##b.        1 Constant —
##  The cost of a single ticket
##2.    Create four print statements that will display the values of the variables and the constant along with labels that describe them
##

#Initialize
movieNm = str("")
numTickets = int(0)
totalTicketPrice = float(0.0)

SINGLE_TICKET = int(10)

#input
name = input("Enter the name of the movie you would like to see:")
numTickets = input("Enter the number of tickets you wish to purchase:")


#process
totalTicketPrice = SINGLE_TICKET * numTickets


#output
print("Feature Film", name)
print("Cost of single ticket", SINGLE_TICKET)
print("Number of Tickets purchased", numTickets)
print("Your Total", SINGLE_TICKET * numTickets)

当您测试代码时，输​​出总是非常错误，我不知道如何修复它。谢谢！

Answer 1

在这一行numTickets = input("Enter the number of tickets you wish to purchase:") 中，当您获得用户输入时，您将获得string，您应该将此输入转换为int，如下所示：

numTickets = int(input("Enter the number of tickets you wish to purchase:"))

看这个例子可能对你有帮助（这个例子发生在你的代码中）：

print('2'*10)
# 2222222222
