def integer_to_english(number):
    if number>=1 and number<=1000:
        a = ['','one','two','three','four','five','six','seven','eight','nine','ten','eleven','twelve','thirteen','fourteen','fifteen','sixteen','seventeen','eighteen','nineteen','twenty ','thirty ','fourty ','fifty ','sixty ','seventy ','eighty ','ninty ']
        if number<=20:
            if number%10==0: return a[number]
            else: return a[number]
        elif number<100:
            b=number-20
            r=b%10
            b//=10
            return a[20+b]+a[r]
        elif number<1000:
            if number%100==0:
                b=number//100
                return a[b]+' hundred'
            else:
                r=number%100
