How to display multiple placemarks and paths?

I'm using PyKml module in order to form kml inside my Python script. I want to display path which consists of array of coordinates and also display all points as placemarks. Currently, I'm trying (without success) to do it following way

 doc = K.kml(
        K.Document(
            K.Placemark(
                 K.Point(
                     K.name("pl1"),
                    K.coordinates("52.4858, 25.9218, 1051.05105105")
                ) 
            ),
            K.Placemark(
                K.name("path1"),
                K.LineStyle(
                  开发者_开发知识库  K.color(0x7f00ffff),
                    K.width(10)
                ),
                K.LineString(
                    K.coordinates(
                        coord_str
                    )
                )
            )
        )
    )

Path looks OK, but when I start adding Placemarks, Google Maps displays only first one. What should I use to display all Placemarks on my path? Do I need some sort of metaprogramming(i.e. add placemarks in object definition automatically)? Or perhaps something else?

This should let you iterate over the objects and associate each point with the lines it terminates:

from pykml.factory import KML_ElementMaker as K
from lxml import etree

#line_points here comes from a geojson object
data = json.loads(open('tib.json').read())
line_points = data['features'][0]['geometry']['coordinates']

_doc = K.kml()

doc = etree.SubElement(_doc, 'Document')

for i, item in enumerate(line_points):
    doc.append(K.Placemark(
        K.name('pl'+str(i+1)),
        K.Point(
            K.coordinates(
                str(item).strip('[]').replace(' ', '')
                )
        )
    )
)

doc.append(K.Placemark(
    K.name('path'),
    K.LineStyle(
        K.color('#00FFFF'),
        K.width(10)
    ),
    K.LineString(
        K.coordinates(
            ' '.join([str(item).strip('[]').replace(' ', '') for item in line_points])
        )
    )
))

s = etree.tostring(_doc)

print s

where line_points is a list of lists like this, with the coordinates:

[[-134.15611799999999, 34.783318000000001, 0],
 [-134.713527, 34.435267000000003, 0],
 [-133.726201, 36.646867, 0],
 [-132.383655, 35.598272999999999, 0],
 [-132.48034200000001, 36.876308999999999, 0],
 [-131.489846, 36.565426000000002, 0],...
