if i read an indented section, its showing section not found.

my file:
[section]
a = 0.3

    [subsection]
    b = 123
import configparser
conf = configparser.ConfigParser()
conf.read("./test.conf")
a = conf['section']['a']
print(a)

Output of a:

[subsection]
b = 123

Expected a : 0.3 only

But Section b is not found
