问题描述
I want to put python script output to HTML using Django with a button.
我想使用带有按钮的 Django 将 python 脚本输出放到 HTML 中。 When the user clicks the button again and it changes the random number again.当用户再次单击该按钮并再次更改随机数时。
import random
num = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
print(random.choice(num))

In your views.py file inside your app (all inside your Django project)... From the function that will display this random number, put:在您的应用程序中的views.py文件中（全部在您的 Django 项目中）...从将显示此随机数的函数中，输入：
from random import choice
def <function_you_are_using> (request):
nums = [1,2,3,4,5]
context = {"number": choice(nums)}
return render(request, '<function_you_are_using>', context)
Then, in your HTML, put:然后，在您的 HTML 中，输入：
<h1>{{ number }}</h1>
That should display the random-choice number.那应该显示随机选择数。 Hope it helps.希望能帮助到你。

You could render this out in a template.您可以在模板中呈现它。 This would take the function you have above and place it into a function based view.这将采用您上面的函数并将其放入基于函数的视图中。 the function will take your list of numbers and assign the random number to the variable random_number, which is then passed in as context (on the return line).该函数将获取您的数字列表并将随机数分配给变量 random_number，然后将其作为上下文传入（在返回行上）。
# views.py
def random_num(request):
num = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
random_number = random.choice(num)
return render(request, 'random-number.html', {'random_number': random_number})
To pass this into the HTML template (see HTML below).将此传递到 HTML 模板（请参阅下面的 HTML）。 This is taking the 'random_number' variable that you assigned in your view and rendering it in place of {{ random_number }} when the page loads.这是采用您在视图中分配的 'random_number' 变量，并在页面加载时将其呈现在 {{ random_number }} 的位置。
<!-- random-number.html -->
<html>
<h1>Random Number: {{ random_number }}</h1>
<form action="{% url 'random-number' %}">
<input type="submit" value="Get New Number"/>
</form>
</html>
Sort of a lazy workaround since the "button" is just refreshing the page to call the function again and generate a new random number.有点懒惰的解决方法，因为“按钮”只是刷新页面以再次调用该函数并生成一个新的随机数。
