Here you go into the function "point" the first time. Inside the 
function you are in an infinite while-loop where you only exit if the 
sum is either 7 ("lose") or equal the given parameter ("win"). Then you 
compare the return value. In the case of "lose" you continue to the next 
elif-statement:

>              stake += bet*2
>              print winmsg
>          elif  point(one+two) == "lose":

Now you go into the function "point" a *second* time, in other words you 
have to throw another 7 to leave the function with the return value 
"lose". But just now you will print out the message for loosing the game:

>              print losemsg
>              player = changePlayer(player)

What you probably want is to go into "point" only once, save the result 
value and check if it's "win" or "lose".
