Is it possible to write this Python 3 If Statement in another, more concise and/or elegant form?

I am wondering if there is an alternative, more elegant, syntax for code to achieve the same result as the below code (which works):

import pandas as pd
path = 'C:/Users/Path/'
name1 = 'David'
name2 = 'Thomas'
switch = 'On'

if switch == 'On':
    df = pd.read_csv(path + name1 + '.csv')
elif switch == 'Off':
    df = pd.read_csv(path + name2 + '.csv')

The kind of thing I am thinking about is this (but this results in a syntax error):

import pandas as pd
path = 'C:/Users/Path/'
name1 = 'David'
name2 = 'Thomas'
switch = 'On'

df = pd.read_csv(path + (if switch == 'On':
                            name1
                        elif switch == 'Off':
                            name2) + '.csv')

The goal is to avoid having to write out multiple lines of very similar code as per the first example!

I would appreciate alternatives and am interested as to why the second approach does lead to a syntax error!

Thanks!...
