#題目：一個數如果恰好等於它的因子之和，這個數就稱為"完數"。例如6=1＋2＋3.編程找出1000以內的所有完數。def suoyou(n):#找到所有因子    s = []    for i in range(1,n+1):        if n % i ==0:            s.append(i)    s = s[:len(s)-1]    x = 0    # print(‘所有銀子‘,s)    for i in s:        x +=i    return xdef zhengchu(n):#因式分解    for i in range(2, n + 1):        if n % i == 0:            k = int(n / i)            m.append(i)            return zhengchu(k)        else:            continue    if m == []:        n = n + 1    else:        y = [str(x) for x in m]        # print (y)        t1 = ‘*‘.join(y)        n1 = eval (t1)        # print(‘suoyou‘,suoyou(int(X)))        if int(n1) == suoyou(int(X)):            print (‘%s 為完數‘% X)for n in range(1,1001):    # print(‘ha‘,n)    X = str(n)    m = []    zhengchu(n)
