如何将这些数据分成两个单独的列表，以便在python中绘制？

# 原始数据
data = [(1, 2), (3, 4), (5, 6), (7, 8)]

# 使用列表推导式将数据分成两个列表
list1 = [item[0] for item in data]
list2 = [item[1] for item in data]

print(list1)  # 输出: [1, 3, 5, 7]
print(list2)  # 输出: [2, 4, 6, 8]

data = [(1, 2), (3, 4), (5, 6), (7, 8), 'invalid']

list1 = []
list2 = []

for item in data:
    try:
        list1.append(item[0])
        list2.append(item[1])
    except (TypeError, IndexError):
        print(f"Skipping invalid item: {item}")

print(list1)  # 输出: [1, 3, 5, 7]
print(list2)  # 输出: [2, 4, 6, 8]
