Example in README does not work

[petrushy]

Hi I'm not getting the example in README.rst to work, using python 2.7.

Added an import of json, and changed to capitals on doc = czml.CZML() and moved bb.show = True from initialization to script.

Import the library

from czml import czml import json

Initialize a document

doc = czml.CZML()

Create and append the document packet

packet1 = czml.CZMLPacket(id='document',version='1.0') doc.packets.append(packet1)

Create and append a billboard packet

packet2 = czml.CZMLPacket(id='billboard') bb = czml.Billboard(scale=0.7) #, show=True bb.show = True bb.image = 'http://localhost/img.png' bb.color = {'rgba': [0, 255, 127, 55]} packet2.billboard = bb doc.packets.append(packet2)

Write the CZML document to a file

filename = "example.czml" with open(filename, 'w') as file: json.dump(doc.data(), file)

I however get an error on last line: 182 183 """ --> 184 raise TypeError(repr(o) + " is not JSON serializable") 185 186 def encode(self, o):

TypeError: <generator object data at 0x0000000004792CA8> is not JSON serializable

Good catch @petrushy. Fix and a new minor version bump have been committed that includes a more explicit write() method, and I tested both the updated write and new read examples in the README in interactive python for 2.7 and 3.3. Everything looks like it's working much better now.

This isn't pushed up to pypi yet; just waiting on Travis Build #53. Once that completes, assuming it passes, I'll push the new version up to pypi and resolve this issue.

Okay, all set! Version 0.3.2 with today's commits are pushed up to pypi.
