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.
The arteries are perceived as carrying oxygenated blood to the tissues, while veins carry deoxygenated blood back to the heart. This is true of the systemic circulation, by far the larger of the two circuits of blood in the body, which transports oxygen from the heart to the tissues of the body.he pulmonary veins carry relatively oxygenated blood from the lungs to the heart. The superior and inferior venae cavae carry relatively deoxygenated blood from the upper and lower systemic circulations, respectively. The portal venous system is a series of veins or venules that directly connect two capillary beds.
