Python无法识别if - Statement

Question

我是Coding的新手，我从Python开始学习如何编码。 我打算编写一个简单的测验，用户选择他们想要玩的测验。 我做了输入（）但它没有转到if - Statement。 代码：

import quiz1
import quiz2
import quiz3
import quiz4

quiz = input("Please choose which Quiz you want to play (1-4): ")
print(quiz)

if quiz == 1:
        quiz1
        #f1 = open(fragebogen1.py)
        #print(f1)
elif quiz == 2:
        print("hello")
elif quiz == 3:
        print("hello")
elif quiz == 4:
        print("hello")

提前致谢

Answer 1

quiz = int(input("Please choose which Quiz you want to play (1-4): ")) 函数返回一个字符串。您需要将用户的输入转换为整数：

if int(quiz) == 1:

Answer 2

在检查之前将输入转换为整数

insert into table_xml -- this table has xmlindex, here i dont want to use xmlindex

select * from some_other_table;
-----------------------------------------------
select * from table_xml, xmltable (...); -- here xmlindex is giving great performance

Answer 3

无法联系到elif == 1，因为您输入了if quiz == 1。 相反，您需要输入elif quiz == 2:。
