You can simplify that to:

5 is already an int, so int(5) == 5.

You're asking the user to enter something and then checking whether its
int value is 1.

Now you're asking the user to enter something _again_ and then checking
whether its int value is 2.
In other words, in order for it to print "Moving east" the following
steps must occur:
1. Ask the user to enter something.
2. Check whether it's 1. It isn't. (Previous condition)
3. Ask the user to enter something.
4. Check whether it's 2. (This condition)

The fix is simple. Ask once:
answer = int(raw_input())
if answer == 1:
...
elif answer == 2:
...
