Munyika yehurongwa, Python yave mutauro unozivikanwa nekureruka kwekushandisa, kuverenga, uye kuchinjika. Pakati pemaraibhurari ayo akawanda, NumPy inomira seimwe yezvishandiso zvine simba zvekubata nhamba yedata, iyo ine akawanda maapplication mundima dzakasiyana, kusanganisira fashoni. Muchinyorwa chino, isu tichanyura mune iyo NumPy Shape basa, tichikurukura syntax yayo uye nekupa mhinduro inoshanda kune dambudziko rinosanganisira kuongororwa kwefashoni mafambiro. Tiri munzira, isu tichaongororawo maraibhurari ane hukama uye mabasa. Saka, ngatitange!
