In Python the assignment (including the augmented assignment) is a
statement, del is a statement, function and class declarations are
statements, import is a statement. Mutating methods like list.sort() and
dict.update() return None to discourage using them in expressions. This
a common knowledge, I don't know who's citation you need.
