我想制作一个简单的应用程序,根据用户输入类型选择,建议艺术家听。我已经连接了lists(流派),它可以使用random.choice从任何列表中打印随机项。但是我希望它仅从用户输入的列表中打印随机项目,而不是从随机列表中打印随机项目。
尝试在elif和else之间进行切换。尝试制作一个for循环,但没有成功。
import random
a= ["x", "y"]
b= ["z", "k"]
print("please choose between a or b")
answer = input ()
if answer == "a":
print("You should check out : " , random.choice(a+b))
elif answer == "b":
print("You should check out : " , random.choice(b))
我希望当用户输入“ a”时输出是列表a
中的随机项,而当用户输入“ b”时输出是列表b
中的随机项,但是输出是列表a
或b
中的随机项,无论用户输入严格是a
还是b
。

我相信您问题的根源是用户输入='a'下的<form id="zodiac">
<label for="month">Month:</label>
<select id="month">
<option value='0' selected>January</option>
<option value='1'>February</option>
<option value='2'>March</option>
<option value='3'>April</option>
<option value='4'>May</option>
<option value='5'>June</option>
<option value='6'>July</option>
<option value='7'>August</option>
<option value='8'>September</option>
<option value='9'>October</option>
<option value='10'>November</option>
<option value='11'>December</option>
</select>
<label for="day"> Day: </label>
<input id="day" type='number' min='1' max='30' value='1'>
<button type='button'>Done</button><br>
<label for="output">Your sign is </label><output id='output'></output>
</form>

位。另外,您可以将提示放入您的a+b
语句中。当我跑步时,对我来说似乎很好:
input()
样本输出:
import random
a = ["x", "y"]
b = ["z", "k"]
answer = input("please choose between a or b \n>>>")
if answer == "a":
print("You should check out : ", random.choice(a))
elif answer == "b":
print("You should check out : ", random.choice(b))
please choose between a or b
>>>a
You should check out : x
尝试尝试获得“ z”,但它会出现:
please choose between a or b
>>>b
You should check out : k
please choose between a or b
>>>b
You should check out : z
是换行符,也是我如何提示"\n"
在输出的下一行显示

我认为问题是您正在使用random.choice(a+b)
而不是random.choice(a)
。下面对我来说很好
import random
a= ["x", "y"]
b= ["z", "k"]
print("please choose between a or b")
answer = input ()
if answer == "a":
print("You should check out : " , random.choice(a))
elif answer == "b":
print("You should check out : " , random.choice(b))
