To replicate what you have above, I would do something like;

quit=False
while not quit:
choice=input('1 for calc, 2 for fib, any other to quit')
if choice==1:
print input('Enter expression: ')
elif choice==2:
a, b, n = 1, 1, input("\nWhat Fibonacci number do you want to go to?
")
while n > 0:
print a
a, b, n = b, a+b, n-1
else:
quit=True
