pandas error:None of ['b_id'] are in the columns

I’m trying to create a dataframe from the following code:

import pandas as pd
from io import StringIO

df = """
 b_id          Rejected                   Remediation                        user
 366           NaN                        38 days 22:05:06.807430            Test
 367           0 days 00:00:05.285239     NaN                                Test
 368           NaN                        NaN                                Test
 371           NaN                        NaN                                Test
 378           NaN                        451 days 14:59:28.830482           Test
 384           28 days 21:05:16.141263    0 days 00:00:44.999706             Test

"""
df= pd.read_csv(StringIO(df.strip()), sep='|')
df.set_index("b_id", inplace = True)

But I received error:

"None of ['b_id'] are in the columns"

Any friends can help ?

>Solution :

Change your separator in read_csv, here \s\s+ (2 or more spaces) seems appropriate:

df= pd.read_csv(StringIO(df.strip()), sep='\s\s+', engine='python')
df.set_index("b_id", inplace = True)

Output:

                     Rejected               Remediation  user
b_id
