1、count():用来统计某一个成员在列表中的出现次数,例如: >>> list1 = [123,456,789] >>> list1 *=5 >>> list1 [123, 456, 789, 123, 456, 789, 123, 456, 789, 123, 456, 789, 123, 456, 789] >>> list1.count(123) 5 1. 2. 3. 4. 5. 6. 2、index():返回该元素的索引...

This is exactly the way we would index elements of a matrix in linear algebra. 这正是我们在线性代数中索引矩阵元素的方法。 We can also slice NumPy arrays. 我们还可以切片NumPy数组。 Remember the indexing logic. 记住索引逻辑。 Start index is included but stop index is not,meaning thatPythonstop...
