本文实例讲述了python判断abundant number的方法。分享给大家供大家参考。具体如下:
abundant number,中文译成:盈数(又称 丰数, 过剩数abundant number)是一种特殊的 自然数,除去它本身以外的一切正约数的和大于它本身。

#checks if a number is abundant or not
#an abundant number is the number of which sum of
#factors(including itself) is greater than twice the number
def abundant(n):
sum_factors=0
for i in range(1,n+1):
if n%i==0:
#finds out the factors
f=i
sum_factors += f
if sum_factors>2*n:
#condition for abundant number
print “this is an abundant number!”
else:
print “this is not an abundant number!”
希望本文所述对大家的python程序设计有所帮助。
