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.
An artery is a blood vessel as well as a vein. Explanation: The difference between an artery and a vein is that an artery takes blood (usually in hight O2, except pulmonary artery that goes to the lungs) away from the heart and a vein brings blood (low O2, except pulmonary vein that comes from the lungs) from the body to the heart.
