嗨,我正在尝试将.dat文件转换为。 CSV,但即时通讯无法。请耐心等待,因为我仍然是python的初学者。

这是我的代码:

import pandas as pd
from io import StringIO 

with open('blk01530.dat','r') as f:
    df = pd.DataFrame(l.rstrip().split() for l in f)

print(df)

这是我遇到的错误

Traceback (most recent call last):
  File "/Users/sunqinan/Desktop/FYP/convertdat.py", line 5, in <module>
    df = pd.DataFrame(l.rstrip().split() for l in f)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pandas/core/frame.py", line 445, in __init__
    data = list(data)
  File "/Users/sunqinan/Desktop/FYP/convertdat.py", line 5, in <genexpr>
    df = pd.DataFrame(l.rstrip().split() for l in f)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf9 in position 0: invalid start byte

请帮忙,因为我已经尝试了几个小时,这就是我的.dat文件的样子

首先,DataFrame获取一个列表,因此您需要进行适当的列表理解。请尝试以下操作:

with open('blk01530.dat', 'r') as f:
    df = pd.DataFrame([l.rstrip() for l in f.read().split()])
