Python将两个数组合并成一个数组，多维数组变成一维数组
c1 = ["Red","Green","Blue"]
c2 = ["Orange","Yellow","Indigo"]
c1.extend(c2)
c1 == ["Red","Green","Blue","Orange","Yellow","Indigo"]c1 = ["Red","Green","Blue"]
c2 = ["Orange","Yellow","Indigo"]
c3 = c1 + c2
c3 == ["Red","Green","Blue","Orange","Yellow","Indigo"]a = [[1,3],[2,4],[3,5]]
a = array(a)
a.flatten()
array([1, 3, 2, 4, 3, 5])声明：该文观点仅代表作者本人，牛骨文系教育信息发布平台，牛骨文仅提供信息存储空间服务。
