pandas read_csv预期列数错误，且CSV文件不完整

您可以使用

names

1,2,12,3,4,2,31,2,3,31,2,3,4,5,6

并尝试阅读它，您会收到错误消息

>>> pd.read_csv(r'D:/Temp/tt.csv')Traceback (most recent call last):...Expected 5 fields in line 4, saw 6

但是，如果传递

names

>>> pd.read_csv(r'D:/Temp/tt.csv', names=list('abcdef'))   a  b  c   d   e   f0  1  2  1 NaN NaN NaN1  2  3  4   2   3 NaN2  1  2  3   3 NaN NaN3  1  2  3   4   5   6

希望能帮助到你。
