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.
They are the veins that return deoxygenated blood from the body into the heart. They both empty into the right atrium. The inferior vena cava (or caudal vena cava in animals) travels up alongside the abdominal aorta with blood from the lower part of the body. It is the largest vein in the body. The superior vena cava (or cranial vena cava in animals) is above the heart, and forms from a convergence of the left and right brachiocephalic veins that contain blood from the head and the arms.
