当多维数组中的元素的属性为空时删除该元素

def remove_empty_elements(arr):
    i = 0
    while i < len(arr):
        if is_empty(arr[i]):
            arr.pop(i)
        else:
            i += 1

def is_empty(element):
    for key in element:
        if element[key] is not None:
            return False
    return True

# 示例多维数组
array = [
    {"name": "John", "age": 25},
    {"name": "Jane", "age": None},
    {"name": None, "age": 30},
    {"name": "Mike", "age": 35}
]

remove_empty_elements(array)
print(array)
