class_docstr: You can try this example as follow:
      $ curl http://localhost:5000/todo1 -d "data=Remember the milk" -X PUT
      $ curl http://localhost:5000/todo1
      {"todo1": "Remember the milk"}
      $ curl http://localhost:5000/todo2 -d "data=Change my breakpads" -X PUT
      $ curl http://localhost:5000/todo2
      {"todo2": "Change my breakpads"}
  
  Or from python if you have requests :
   >>> from requests import put, get
   >>> put('http://localhost:5000/todo1', data={'data': 'Remember the milk'}).json
   {u'todo1': u'Remember the milk'}
   >>> get('http://localhost:5000/todo1').json
   {u'todo1': u'Remember the milk'}
   >>> put('http://localhost:5000/todo2', data={'data': 'Change my breakpads'}).json
   {u'todo2': u'Change my breakpads'}
   >>> get('http://localhost:5000/todo2').json
   {u'todo2': u'Change my breakpads'}
