When you exit reroll() you always go into navy()

Because you have nothing to stop it going into reroll().
Thee is no if statement, it will always, without fail exit reroll
and go into navy. (It may call upp() in between times but it
will nonetheless go into navy after reroll finishes.)

You don't really need to return therse since they are the
global values initialised at the top of the code.

You don't need the try/except since the is/elif/else will catch all
possible
cases. BUT you are assigning out to the return value of reroll() but
reroll()
never returns a value. So out will always equal None. This isn't much
of a problem since you never use out anyway! You don't really need
this
function you could replace it with a while loop at the top level.
Your use of nested calls is what is giving your odd behaviouir.
You call upp()
Then you call reroll()
Inside reroll() you either call career() or call upp() again or call
reroll() again
If you call career() then, when it exits, you will exit reroll() and
then call navy().
If you call upp() then, when it exits, you will exit reroll() and then
call navy().
If you call reroll() then, when it exits, you will exit the outer
reroll() and then call navy().
So whatever happens in reroll() you eventually wind up calling navy()

This does nothing.

b[0] will be a character. You are comparing a character to a string.
It will never equate.

Same for these

The except will never get called(unl;ess one of the called
functions raises an exception, which is fairly unlikely.

Again, this does nothing

You could simplify that to one line with:

Or if you really want a separate line:

This is an unusual way of inserting entries to a list. It would be
more
common to use append or insert, as in:
skills.append('Ships Boat')

You can almost certainly tidy this lot up using better data structures
then it becomes a case of indexing into the data rather than all the
if/elif steps.

In general you will find life easier if you start with a simpler
version of your
program (only two or three characeristics/skills etc) and get the
overall
structure right. Its easier to debug and less code to write. Once its
basically
working adding extra features is easy.
