    @app.route('/users/<string:name>/')
    def hello(name):
        namesource = request.args.get('name')
        return "Hello {}!".format(name)

print(namesource)  # here am trying to get the sitring/value in name source but i can't because it no       variable defines

api.add_resource(Users, name='users')
# For Running our Api on Localhost
if __name__ == '__main__':

You are trying to access the variable namesource outside of the function hello . You can't do that. You can access the variable name outside of the function hello because it is a parameter of the function. You can fix it by making a global variable.

app = Flask(__name__)
api = Api(app)

namesource = None

class Users(Resource):
    @app.route('/users/<string:name>/')
    def hello(name):
        global namesource
        namesource = request.args.get('name')
        return "Hello {}!".format(name)

print(namesource)

api.add_resource(Users, name='users')
# For Running our Api on Localhost
if __name__ == '__main__':
    app.run(debug=True)
