zip()
a = [1,2,3] b = [4,5,6] c = [4,5,6,7,8] zipped = zip(a,b) # 返回一个对象 zipped <zip object at 0x103abc288> list(zipped) # list() 转换为列表 [(1, 4), (2, 5), (3, 6)] list(zip(a,c)) # 元素个数与最短的列表一致 [(1, 4), (2, 5), (3, 6)]
a1, a2 = zip(zip(a,b)) # 与 zip 相反，zip() 可理解为解压，返回二维矩阵式 list(a1) [1, 2, 3] list(a2) [4, 5, 6]
