Using a for loop, traverse through all the data elements and after encountering every element, increment the counter variable by 1. 使用for循环,遍历所有数据元素,遇到每个元素后,将计数器变量加1。 Thus, the length of the array will be stored in the counter variable as the variable will represent...

Finally, you need to test that the length of each dimension is either (drawn from) a common length, or 1. A trick for doing this is to first mask the array of NumPy “shape-tuples” in places where it equals one. Then, you can check if the peak-to-peak (np.ptp()) column-...
