角度迭代不起作用(只取第一个)

# 示例代码：检查迭代器
my_list = [1, 2, 3, 4, 5]

for item in my_list:
    print(item)

# 手动实现迭代器
class MyIterator:
    def __init__(self, data):
        self.data = data
        self.index = 0

    def __iter__(self):
        return self

    def __next__(self):
        if self.index >= len(self.data):
            raise StopIteration
        value = self.data[self.index]
        self.index += 1
        return value

my_iterator = MyIterator(my_list)

for item in my_iterator:
    print(item)

# 示例代码：检查逻辑错误
my_list = [1, 2, 3, 4, 5]

for item in my_list:
    if item % 2 == 0:
        break
    print(item)

# 修正后的代码
for item in my_list:
    print(item)

# 示例代码：检查数据结构
my_list = []  # 空列表

for item in my_list:
    print(item)

# 修正后的代码
my_list = [1, 2, 3, 4, 5]

for item in my_list:
    print(item)
