for row in reader: UnicodeDecodeError: 'gbk' codec can't decode byte 0xa7 in position 111: illegal multibyte sequence

这个错误通常是因为在读取文件时使用了错误的编码方式。在Python中，默认的编码方式是UTF-8，但是如果你的文件是以GBK编码保存的，那么就需要在读取文件时指定编码方式为GBK。

你可以尝试在读取文件时指定编码方式为GBK，例如：

import csv

with open('file.csv', 'r', encoding='GBK') as f:
    reader = csv.reader(f)
    for row in reader:
        print(row)

如果你不确定文件的编码方式，可以尝试使用一些工具来检测文件的编码方式，例如chardet库。

for row in reader: UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position 70: illegal multibyte sequence

这个错误信息意味着在使用`gbk`编解码器解码某个字节序列时，解码器无法处理`0xad`字节，因为它是不合法的多字节序列。这通常意味着文件编码和使用的编解码器不匹配。要解决这个问题，你可以尝试以下几个步骤：
1.确认文件编码是否正确，比如使用`utf-8`编码，如果不是，可以将文件另存为`utf-8`编码。
2.在读取CSV文件时指定正确的编解码器，例如：`csvfile = open(filename, 'r', encoding='utf-8')`。
如果这些步骤都没有解决问题，你可能需要检查文件是否已经损坏或者文件是否存在其他问题。

for row in reader: UnicodeDecodeError: 'gbk' codec can't decode byte 0x99 in position 1161: illegal multibyte sequence

This error occurs when the CSV file being read contains characters that cannot be decoded using the specified codec (in this case, 'gbk'). The byte 0x99 is an example of such a character.

To fix this error, you need to determine the correct codec for the CSV file. You can try opening the CSV file in a text editor and checking the encoding used in the file properties. Alternatively, you can try different codecs until you find one that works.

Once you have determined the correct codec, you can specify it when opening the CSV file. For example, if the correct codec is 'utf-8', you can open the CSV file like this:

import csv

with open('file.csv', newline='', encoding='utf-8') as csvfile:
    reader = csv.reader(csvfile)
    for row in reader:
        # process row

Note that the `encoding` parameter is set to 'utf-8' instead of 'gbk', which was causing the error.
