Conditions can be more complicated than a single question, and if statements can also be combined with multiple questions and different responses based on the answer to each question. 1 2 3 4 age = 13 if age > 20: print('You are too old!') #The lines following the colon must be in...
It’s easy to index and slice NumPy arrays regardless of their dimension,meaning whether they are vectors or matrices. 索引和切片NumPy数组很容易,不管它们的维数如何,也就是说它们是向量还是矩阵。 With one-dimension arrays, we can index a given element by its position, keeping in mind that indice...
