发生异常: error unpack requires a buffer of 36 bytes File "D:\tdx解析分钟数据.py", line 13, in parse_lc5 close_price, turnover, volume, _ = struct.unpack('<HHfffffii4x', data[start:start+32]) File "D:\tdx解析分钟数据.py", line 39, in <module> lc5_data = parse_lc5('D:\\sz000001.lc5')

这个异常的意思是：在解包数据时，需要的缓冲区大小是 36 字节，但实际传入的数据不足 36 字节，因此无法解包。你需要检查一下你程序中的数据来源和数据传输是否正确，是否确保数据完整。也可以尝试检查一下你的数据文件是否存在损坏或者数据格式是否正确。另外，你也可以在代码中加入一些异常处理的方法，这样可以更好地帮助你定位问题。

struct.error: unpack requires a buffer of 4 bytes python异常捕获

这个异常通常是因为尝试解包一个长度不足4个字节的字节串所引起的。你可以在代码中使用try-except语句来捕获这个异常，例如：

try:
    # your code here
except struct.error:
    print("Error: unpack requires a buffer of 4 bytes.")

在try语句块中，你需要确定使用`struct.unpack()`函数时提供的字节串长度是否足够。如果长度不足4个字节，则会引发`struct.error`异常。在except语句块中，你可以输出一条错误消息，告诉用户出现了什么问题。

struct.error: unpack requires a buffer of 4 bytes

This error is typically encountered when attempting to unpack a binary data stream that is smaller than expected. The unpack function in Python is used to extract data from a packed binary string, which consists of a series of bytes that have been encoded in a specific format.

In this case, the error message indicates that the unpack function was expecting a buffer of at least 4 bytes, but the actual buffer size was smaller. This could be due to a few different reasons, such as:

- The binary data stream was truncated or corrupted, causing it to be smaller than expected.
- The format string used to unpack the data specifies more fields than are actually present in the binary data stream.
- The code attempting to unpack the binary data is using the wrong format string, causing it to interpret the data incorrectly.

To resolve this error, you should first check that the binary data stream being unpacked is complete and not corrupted. You can also try modifying the format string used to unpack the data, or double-check that it matches the expected format of the binary data.
