I understand the following:

In [79]: instansie
instansie
Out[79]: 'Mangosuthu Technikon'

In [80]: t = [x.alt_name for x in lys]
t = [x.alt_name for x in lys]

In [81]: t
t
Out[81]: []

In [82]: t.append(instansie)
t.append(instansie)

In [83]: t
t
Out[83]: ['Mangosuthu Technikon']

But then why does the following behave like this:

In [84]: t = [x.alt_name for x in lys].append(instansie)
t = [x.alt_name for x in lys].append(instansie)

In [85]: t
t

In [86]: type t
type t
-------> type(t)
Out[86]: NoneType

Regards
Johann
