因此，请阅读csv，但将分隔符覆盖到选项卡上，这样它就不会尝试拆分名称：
In[7]:
import pandas as pd
import io
t="""Anne,Beth,Caroline,Ernie,Frank,Hannah
Beth,Caroline,David,Ernie
Caroline,Hannah
David,,Anne,Beth,Caroline,Ernie
Ernie,Anne,Beth,Frank,George
Frank,Anne,Caroline,Hannah
George,
Hannah,Anne,Beth,Caroline,David,Ernie,Frank,George"""
df = pd.read_csv(io.StringIO(t), sep='\t', header=None)
df
Out[7]:
0
0 Anne,Beth,Caroline,Ernie,Frank,Hannah
1 Beth,Caroline,David,Ernie
2 Caroline,Hannah
3 David,,Anne,Beth,Caroline,Ernie
4 Ernie,Anne,Beth,Frank,George
5 Frank,Anne,Caroline,Hannah
6 George,
7 Hannah,Anne,Beth,Caroline,David,Ernie,Frank,Ge...
现在str.split，我们可以使用withexpand=True将名称扩展到自己的列中：
In[8]:
df[0].str.split(',', expand=True)
Out[8]:
0 1 2 3 4 5 6 7
0 Anne Beth Caroline Ernie Frank Hannah None None
1 Beth Caroline David Ernie None None None None
2 Caroline Hannah None None None None None None
3 David Anne Beth Caroline Ernie None None
4 Ernie Anne Beth Frank George None None None
5 Frank Anne Caroline Hannah None None None None
6 George None None None None None None
7 Hannah Anne Beth Caroline David Ernie Frank George
因此，为了清楚起见，将您的read_csv行修改为此：
df = pd.read_csv(infile, header=None, sep='\t')
然后做str.split上面的
