python_计算1+……+100中偶数和
如何计算1+……+100中偶数和?
1. 把奇数去掉,通过if,判断累加数除以2的余数,是否为1,判断是否是奇数
2. 通过continue 跳过对奇数的累加
#!/usr/bin/python3 def sum_go(sum_to): '''计算1+……+100中偶数和''' count = 0 sum_all = 0 while count <= sum_to: count += 1 if count % 2 == 1: continue else: print(count) sum_all += count return sum_all if __name__ =='__main__': result = sum_go(sum_to=100) print('结果是:%s' % result)
