Google Static Maps API: Creating a Static Map with Paths

I am trying to create a google static map with some points on it and some lines connecting these points (I am going to draw lines in accordance with the directions of movement soon, but this will happen later). Right now, I have code like this to create a url:

def getStaticMapAddress(self, route):
    url = "http://maps.google.com/maps/api/staticmap?center="+str(route[0].location.lat)+","+str(route[0].location.lng)+"&zoom=6&size=400x400&markers="
    i=0
    while i<len(route):
        url += str(route[i].location.lat)+","+str(route[i].location.lng)
        i=i+1
        if (i < len(route)):
            url += "|"
    url += "&path=color:0xff0000ff&weight:5"
    i=0
    while i<len(route):
        url += "|"+str(route[i].location.lat)+","+str(route[i].location.lng)
        i+=1
    url += "&sensor=false"
    return url

In this function, a “route” is a list of users with associated locations. With my test data, this URL was generated:

http://maps.google.com/maps/api/staticmap?center=50.8202008,-0.1324898&zoom=6&size=400x400&markers=50.8202008,-0.1324898|51.447341,-0.0761212|51.4608947,-2.5884312&path=color:0xff0000ff&weight:5|50.8202008,-0.1324898|51.447341,-0.0761212|51.4608947,-2.5884312&sensor=false
