Is this rule exclusive for partitive articles?

Question

Is it correct to say "Je ne Viens pas de natation" as a negative form of "Je viend de la natation"

Answer

Bonjour Anish,
This is the lesson statement that most aptly fits your question:
ATTENTION: This rule does NOT apply to sentences using the verb être, with which the partitive article doesn't change.
C'est du sel de Guérande ? -Non, ce n'est pas du sel de Guérande.
Is that Guerande salt? -No, it's not Guerande salt.
C'est de l'huile d'olive ? -Non, ce n'est pas de l'huile d'olive.
Is this olive oil? -No, this is not olive oil.

J'espère que cela vous aidera.
