#Checks If a number is abundant or not#an abundant number are the number of which sum of#factors (including itself) is great Er than twice the numberdef abundant (n):  sum_factors=0 for  i in range (1,n+1):    if n%i==0:    #finds out the FA Ctors      f=i      sum_factors + f        if sum_factors>2*n:  #condition for abundant number    print Abundant number! "  else:    print "This isn't an abundant number!"
