I am sure this belongs to the Gourd family. But which one? Hopefully I shall see the fruit sometime ( it is not growing in my house). Correction – could be the pumpkin as Swaram has pointed out – same family though – Cucurbitaceae
Botanical name: Cucurbita pepo Family: Cucurbitaceae (Pumpkin family)
Synonyms: Cucumis pepo
Will write more about the vine after hopefully confirming the fruit.
