Question

使用python 3完成菜鸟。我有一些代码，无法弄清楚为什么我会继续得到我的输出。出于某种原因，elif语句未被识别。这是输出优先和下面的代码：

3
Your fortune for today is:  
Please press enter to end

#Program for fortune cookies

var1 = "It's going to be a good day"
var2 = "You'll have a long life"
var3 = "Your life will be short"
var4 = "Things will be good"
var5 = "Life will be fun"
import random

randNum = random.randint(1, 5)
statement = ""
print(randNum)
if randNum == 1:
    statement = var1
elif randNum == 2:
    statement = var2
elif randNum == 3:
    statement == var3
elif randNum == 4:
    statement == var4
elif randNum == 5:
    statement == var5

print("Your fortune for today is: ", statement)
input("Please press enter to end")

Answer 1

您没有将varx分配给statement（在某些情况下，分别为3,4和5），但需要进行比较。只需改变所有：

statement == varx

要：

statement = var3

除此之外，似乎有效。

Answer 2

检查行：

elif randNum == 3:
    statement == var3
elif randNum == 4:
    statement == var4
elif randNum == 5:
    statement == var5

'=='用于检查相等性，'='用于分配变量。

Answer 3

问题是例如

＆＃13;

statement == var5

＆＃13;

转让声明。

祝你好运！
