Python活力练习Day19

Day19:给定一个整数数组nums，请你返回其中位数为偶数的数字的个数

　　eg：input :  nums = [12,345,2,6,7896]

　　　　output : 2(其中12和7896是偶数位数）

def findNumbers(nums):
    #方法一
    num = [str(i) for i in nums]
    count = 0
    i = 0
    while i < len(nums):
        if len(num[i]) % 2 == 0:
            count += 1
        i += 1
    return count

    #方法二
    #num = map(str,nums)
    #count = 0
    #for i in num:
    #if len(i) % 2 == 0:
        #count += 1
            #return count　　　
if __name__ == "__main__":
    nums = [12,345,2,6,7896]
    print(findNumbers(nums))

输出结果：2
