Flow control in a simple Python script

I am trying to make a simple game.

The logic is like this: "There are five doors, each numbered 1 to 5. Users will be asked to input any one number. For example, if they enter "1", the GoldRoom will be opened (and the associated class will be processed)."

Now, I have defined one class, GoldRoom(), and for testing, entered "1". The processing happens as expected. However, when I enter "2" as my choice, the processing still happens, instead of the print statement, i.e the else statement is not getting executed.

Where am I going wrong?
