If you do not know how to perform the next step on the transpose operation solution of the Python matrix transpose, You need to transpose a two-dimensional array to swap the rows and columns of the Python matrix transpose. in this way, you can complete the application operations you need. The following are the specific operations of the article. You need to trans

In Python, sometimes we use arrays to manipulate data to greatly improve the efficiency of data processing.Like the vectorization operation of R, the operation of the data tends to be simplified, and in Python it is possible to use the NumPy module for array and vector calculations.Let's look at the simple example below.Import NumPy as NPData=np.array ([2,5,6,8,3
