How to select range of columns in a dataframe based on their name and not their indexes?

Question

In a pandas dataframe created like this:

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.randint(10, size=(6, 6)),
                  colu         


        

Answer 1

This seems way too easy so perhaps I'm doing something wrong.

df <- data.frame(c1=1:6, c2=2:7, c3=3:8, c4=4:9, c5=5:10, c6=6:11,
                 row.names=c('r1', 'r2', 'r3', 'r4', 'r5', 'r6'))


df[c('r1','r2'),c('c1','c2')]

   c1 c2
r1  1  2
r2  2  3
