Is it posible to make a random case chooser in Python?

I mean for example

switch (month) {

            case 1:  monthString = "January";

                     break;

            case 2:  monthString = "February";

                     break;

            case 3:  monthString = "March";

                     break;

            case 4:  monthString = "April";

                     break;

            case 5:  monthString = "May";

                     break;

            case 6:  monthString = "June";

                     break;

            case 7:  monthString = "July";

                     break;

            case 8:  monthString = "August";

                     break;

            case 9:  monthString = "September";

                     break;

            case 10: monthString = "October";

                     break;

            case 11: monthString = "November";

                     break;

            case 12: monthString = "December";

                     break;

            default: monthString = "Invalid month";

                     break;

        }

and somehow make it random to choose, i mean the case is chosen randomly.
