This looks confusing. Are you sure you are reading the right sampling.cfg?

It looks like the parser does not expand tabs, and your problem may be
mixing tabs and spaces:
$ cat demo.py
import configparser
data = """\
[Sampling]
\talpha = 1
\tbeta = 2
\tgamma = 3
\tdelta = 4
"""
print "what you see:"
print data.expandtabs(4)
print "what the parser sees:"
print data.replace("\t", " ")
with open("sampling.cfg", "w") as f:
f.write(data)
cp = configparser.ConfigParser(
interpolation=configparser.ExtendedInterpolation()
)
cp.read("sampling.cfg")
for item in cp.items('Sampling'):
print item
$ python demo.py
what you see:
[Sampling]
alpha = 1
beta = 2
gamma = 3
delta = 4
what the parser sees:
[Sampling]
alpha = 1
beta = 2
gamma = 3
delta = 4
(u'alpha', u'1')
(u'beta', u'2\ngamma = 3')
(u'delta', u'4')
