[FIXED] keyError in pandas on selecting multiple columns

Issue

I am having a weird error when selecting multiple columns in pandas dataframe. Here is the code:

import pandas as pd
df = pd.read_csv("./Dataset/train.csv", engine='python')
df['eviv1', 'v2a1']

I get this error message: KeyError: ('eviv1', 'v2a1') but I don't get an error message when running

df['eviv1']

df[v2a1]

separately. PS: I am using python 3 and Jupyter Notebook with pandas version 0.23.0.

Solution

The column names (which are strings) cannot be sliced in the manner you tried. Please try this,

df[['eviv1', 'v2a1']]
