thanks very much, great response really really appreciated it and now i
understand. i hate to ask again but can you see why it won't print the 'enter
and amount over 50' in the right place??
Computers are unfailingly stupid machines. They will do whatever wrong thing
you tell them to do every single time.
<snip>def main(): amount=0 while amount<50: amount = input('how
much do you want to change:')
print 'enter an amount over €50: ' else:
total=exchange(amount) print 'Your exchange comes to: ',total
Sometimes it helps writing out the logic in steps before you translate it to
code. In this case my guess is that these are the steps you want:
1. Get a value from the user (you're still using input - stop that, it's
dangerous! input is only a good function in 3.x where it replaces raw_input)
2. If the value is less than 50, tell the user to enter an amount > 50 and
repeat step 1
3. Otherwise, exchange the amount and display that.
Right now, these are the steps that you're doing:
1. Get a value from the user
2. Display the error message
3. If the value is < 50, go to 1
4. exchange the amount
5. display the amount.
