我在使用 python pandas 时遇到了一个非常奇怪的错误：
import pandas as pd
df = pd.read_csv('C:\Temp\test.csv', index_col=None, comment='#', sep=',')
test.csv 是在记事本中创建的一个非常简单的 CSV 文件：
aaa,bbb,date
hhhhh,wws,20220701
现在我收到错误：
File "C:\test\untitled0.py", line 10, in <module>
df = pd.read_csv('C:\temp\test.csv', index_col=None, comment='#', sep=',')
