问题场景
1、使用Pandas处理文件，报错 UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 0: invalid continuation by
Traceback (most recent call last): File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\util\_decorators.py", line 311, in wrapper return func(*args, **kwargs) File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\io\parsers\readers.py", line 586, in read_csv return _read(filepath_or_buffer, kwds) File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\io\parsers\readers.py", line 482, in _read parser = TextFileReader(filepath_or_buffer, **kwds) File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\io\parsers\readers.py", line 811, in __init__ self._engine = self._make_engine(self.engine) File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\io\parsers\readers.py", line 1040, in _make_engine return mapping[engine](self.f, **self.options) # type: ignore[call-arg] File "D:\workspace_py\pandas_learning\venv\lib\site-packages\pandas\io\parsers\c_parser_wrapper.py", line 69, in __init__ self._reader = parsers.TextReader(self.handles.handle, **kwds) File "pandas\_libs\parsers.pyx", line 542, in pandas._libs.parsers.TextReader.__cinit__ File "pandas\_libs\parsers.pyx", line 734, in pandas._libs.parsers.TextReader._get_header File "pandas\_libs\parsers.pyx", line 843, in pandas._libs.parsers.TextReader._tokenize_rows File "pandas\_libs\parsers.pyx", line 1917, in pandas._libs.parsers.raise_parser_error UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 0: invalid continuation byte
2、目前的代码是这样的：
info = pd.read_csv("xxx.csv", delimiter=",", encoding="utf-8", names=["xxx","xxx"])
解决办法
其实这个问题非常容易解决：
方法一：只需要将endoding改成你的csv文件的编码格式就可以了。
方法二：将csv文件格式转成你想要的格式，跟代码保持一致即可。
那查看csv文件的编码格式呢？
右击文件，使用Notepad++打开：
查看右下角：
修改代码：
info = pd.read_csv("xxx.csv", delimiter=",", encoding="gb2312", names=["xxx","xxx"])
这样子就不会报错了。当然，你也可以！
当然，你将csv文件转换成其他格式也是可以的，比如改成utf-8格式：
