根据条件对数据帧中的正负连续元素进行计数

def count_continuous_elements(data_frame):
    count = 0
    for i in range(1, len(data_frame)):
        if (data_frame[i] > 0 and data_frame[i-1] > 0) or (data_frame[i] < 0 and data_frame[i-1] < 0):
            count += 1
        else:
            count = 1
    return count

# 示例数据帧
data_frame = [1, 2, -3, -4, 5, 6, 7, -8, -9, -10]
result = count_continuous_elements(data_frame)
print("正负连续元素的个数为:", result)
