如何将python中的列表提供给javascript？

我对Javascript相当陌生。我想知道，导入Python生成的列表是如何工作的？下面是我的想法的大致版本，我正在尝试使用javascript将3个列表导入到HTML文件中（如果任何语法不正确，请提前道歉）：

函数createMarkers（）{
//导入由headline.py生成的文章列表
//从headline.py生成的导入URL
//导入由headline.py生成的坐标
对于（i=0；i<25；）{
物品名称=物品清单[i]
url=url[i]
坐标=坐标[i]
var marker[i]=WE.marker（[coordinate]）.addTo（earth）；
bindpoop（“article_name
，{maxWidth:520，closeButton:true}）；
}
}

我是否需要实现某种web框架来执行python代码并将其输入到javascript代码中？我将如何进行此操作？

您研究过模板语言吗？我使用Jinja2解决了类似的问题

这里有一些。 这里有一个教程

下面是一个例子

使用Jinja2将变量标记注入HTML

Python代码：

import webapp2 # Le framework
import json    # This is used to return the dictionary in a native (to JS) way
import jinja2  # The glue

# This example uses webapp2, but could be easily adapted to other frameworks.
jinja_environment = jinja2.Environment(
    # sets the folder "templates" as root folder for html (can be tweaked to match you layout):
    loader=jinja2.FileSystemLoader('templates')) 

class Marker():
"""
creates marker objects that can then be rendered on the map.
"""

def __init__(self, latlng, title):
    # below we split the comma-separated latlng into two values and store in an array.
    coords = str(latlng).split(',')
    self.lat = coords[0]
    self.lng = coords[1]
    self.title = title

class MainHandler(webapp2.RequestHandler):
    def get(self):
        # assembling the coordinates and descriptions into an array of Marker objects
        markers = []
        for marker in list_of_markers:
            markers.append(Marker(latlng="coordinates go here in format 'latitude, longitude'",
                                  title="Marker title goes here")

        for marker in markers:
           t_dict = {}
           t_dict['m_title'] = marker.title
           t_dict['m_lat'] = marker.lat
           t_dict['m_lng'] = marker.lng
           temp.append(t_dict)
        json_markers = json.dumps(temp)

        template_values = {'markers' :json_markers}

        template = jinja_environment.get_template('index.html')
            self.response.out.write(template.render(template_values))

# Initializing the webapp:
application = webapp2.WSGIApplication([('/', MainHandler)], debug=False)

// To be added to the initialize() function of the maps JS:
data = {{ markers }} 

// Iterating over list of points to create markers:
data.forEach(function(p) {
     var point = new google.maps.LatLng(p.m_lat, p.m_lng);
     var marker = new google.maps.Marker({position: point,
         map: map,
         title: p.m_title,
         //animation: google.maps.Animation.DROP,
     });
 });

Javascript代码：

import webapp2 # Le framework
import json    # This is used to return the dictionary in a native (to JS) way
import jinja2  # The glue

# This example uses webapp2, but could be easily adapted to other frameworks.
jinja_environment = jinja2.Environment(
    # sets the folder "templates" as root folder for html (can be tweaked to match you layout):
    loader=jinja2.FileSystemLoader('templates')) 

class Marker():
"""

def __init__(self, latlng, title):
    # below we split the comma-separated latlng into two values and store in an array.
    coords = str(latlng).split(',')
    self.lat = coords[0]
    self.lng = coords[1]
    self.title = title

class MainHandler(webapp2.RequestHandler):
    def get(self):
        # assembling the coordinates and descriptions into an array of Marker objects
        markers = []
        for marker in list_of_markers:
            markers.append(Marker(latlng="coordinates go here in format 'latitude, longitude'",
                                  title="Marker title goes here")

        for marker in markers:
           t_dict = {}
           t_dict['m_title'] = marker.title
           t_dict['m_lat'] = marker.lat
           t_dict['m_lng'] = marker.lng
           temp.append(t_dict)
        json_markers = json.dumps(temp)

        template_values = {'markers' :json_markers}

        template = jinja_environment.get_template('index.html')
            self.response.out.write(template.render(template_values))

# Initializing the webapp:
application = webapp2.WSGIApplication([('/', MainHandler)], debug=False)

// To be added to the initialize() function of the maps JS:

// Iterating over list of points to create markers:
data.forEach(function(p) {
     var point = new google.maps.LatLng(p.m_lat, p.m_lng);
     var marker = new google.maps.Marker({position: point,
         map: map,
         title: p.m_title,
         //animation: google.maps.Animation.DROP,
     });
 });

如何运行javascript？如果它是在客户端浏览器中执行的（如果不使用node.js或rhino或其他东西，通常是这样）您无法从那里运行python代码，因为您无法访问客户端计算机。在这种情况下，您需要对web服务器进行AJAX调用，以便为您执行代码并将其反馈给客户端。这当然也取决于您的服务器端实现。您如何为您的应用程序提供服务？我希望使用类似VPS的e Digitalocean托管并运行Python代码。javascript位于HTML文档中。这是否意味着我需要进行AJAX调用（不管是什么）？非常感谢！我以前从未听说过这种语言…所以它非常新，但我会试一试。听起来和我需要的完全一样！这与Python或Flask不同吗？@PythonScraper此示例使用webapp2而不是Flask，但两者高度可互换（至少对于此任务而言）。如果您想要使用烧瓶的示例，只需留下注释。：）
