How do we determine the number of days for a given month in python. Use calendar.monthrange: >>> from calendar import monthrange >>> monthrange(2011, 2) (1, 28) Just to be clear, monthrange supports leap years as well: >>> from calendar import monthrange >>> monthrange(2012, 2) (2, 29)
The Vena Cava is the vein the carries the blood from the body back to the heart. The Aorta is the artery that carries the blood out of the heart into the body. More blood fits â¦ in the entire body than in the heart alone. The Vena Cava carrys de oxygenated blood that is returning from the body and into the right atruim of the heart and the Aorta is the largest artery of the body which tr â¦ ansports oxygenated blood to the rest of the body.     Hope this helps.
