Topological Vector Spaces, chapter III, § 3. Spaces of continuous linear mappings
— Let E be a semi-normed space, and F a Banach (resp. Fréchet) space. The space is a Banach (resp. Fréchet) space. In particular, the dual of a semi-normed space is a Banach space.
Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
