Multiple jinja2 extensions?

Question

I want to add multiple jinja2 etensions but I don't know the syntax. This is my current config:

config = {  'webapp2_extras.sessions': {
    'cookie_name': '_simpleauth_sess',
    'secret_key': SESSION_KEY
  },
  'webapp2_extras.auth': {
    'user_attributes': []
  },'webapp2_extras.jinja2': {'template_path': 'templates',
          'filters': {'timesince': filters.timesince,
          'datetimeformat': filters.datetimeformat,
    'slugify_montao' : filters.slugify_montao,
'format_datetime_human' : filters.format_datetime_human,
'default_if_none' : filters.default_if_none,
'datetimeformat_viewad': filters.datetimeformat_viewad,
'datetimeformat_jinja': filters.datetimeformat_jinja,
},
          'environment_args': {'extensions': ['jinja2.ext.i18n']}},
          'webapp2_extras.sessions': {'secret_key': 'my-245-key'}}

I want to add the entension env = Environment(extensions=['jinja2htmlcompress.SelectiveHTMLCompress']) but I don't know how to have more than one. Can you show me?

Thank you

Update

Seeing the answer below, I've edited my config object to this:

config = { 'webapp2_extras.sessions': { 'cookie_name': '_simpleauth_sess', 'secret_key': SESSION_KEY }, 'webapp2_extras.auth': { 'user_attributes': [] },'webapp2_extras.jinja2': {'template_path': 'templates', 'filters': {'timesince': filters.timesince, 'datetimeformat': filters.datetimeformat, 'slugify_montao' : filters.slugify_montao, 'format_datetime_human' : filters.format_datetime_human, 'default_if_none' : filters.default_if_none, 'datetimeformat_viewad': filters.datetimeformat_viewad, 'datetimeformat_jinja': filters.datetimeformat_jinja, }, 'environment_args': {'extensions': ['jinja2.ext.i18n', 'jinja2htmlcompress.SelectiveHTMLCompress']}}, }

Answer 1

Multiple extensions can be specified as additional elements of the original list.

...
'environment_args': {'extensions': ['jinja2.ext.i18n', 
                                    'jinja2htmlcompress.SelectiveHTMLCompress']}
...

I have to say, though, your config dictionary appears to be irregularly formatted.
One problem in particular is that you appear to have two 'webapp2_extras.sessions' keys which will not work.
