Worked fine for me on Linux... made two suggested changes: 1) use
raw_input(), not input(), 2) check user input for errors. Sorry, I don't
know how to say "Enter a number between 0 and 500" in whatever language
this is in (German?)

 
#!/usr/bin/env python
while 1:
    bedrag = raw_input ( 'Geef bedrag tussen 0 en 500 eurocent: ' )
    try:
        bedrag = int( bedrag )
    except ValueError:
        print "Enter a number between 0 and 500"
    else:
        if bedrag < 0 or bedrag > 500:
            print "Enter a number between 0 and 500"
        else:
            break
    

for munt in 200, 100, 50, 20, 10, 5, 2, 1 :
    aantal = 0

    while bedrag >= munt :
        aantal = aantal + 1
        bedrag = bedrag - munt

    if aantal > 0 :
        print aantal, 'x', munt
-- 
/d/
