matrix when you calculate Np.dot (A, A.T). The shape of A is (5, 1), and a. The shape of T is (1, 5).A.shape = (5,) This is an array of rank 1, not a row vector or a column vector. Many students appear to be difficult to debug bugs are from the rank of 1 arrays.In addition, if you do a lot of things in the code, you may not remember or are unsure of how a is, use assert (A.shape = = (5,1)) to check the dimensions of your matrix.If you get (5,) you can reshape it into (5, 1) or (1, 5), reshape i

a better solution, Please scream. Note the following: 1. For the sake of extensiveness, I used the information in the info_list list as an example. For specific use, you only need to modify info_list and URL 2. To run this program, Python needs to be installed in advance. Just install Google. **************************************** **************************************** ***************************** Today (Oct 17), I was very happy to have helpe

Python crawls the JQuery course of w3shcool and stores it locally. Recently, I am busy looking for a job. In my spare time, I am also looking for crawlers to practice, write code, and know that I am a newbie. But I need to do more exercises. Shushan has a path to work diligently. You can introduce automation, functions, and interfaces to me if you have a test pitfall. First of all, we have a clear requireme

But now you can use another method. is to download to local manual input. It only takes one time to be enough.　Because the landing is successful, you can manipulate other things at will.

sorted method to sort by reading the key-value pair in the for Loop. Examples are as Follows:>>> for key in sorted (list (d.keys ())): ... print (key, ' = = ', d[key]) ... a = 1b + 2This section introduces a dictionary of one of Python's built-in types, a dictionary as an unordered collection of data stored in the form of Key-value pairs, fast searching, support for arbitrary nesting, growth and shortening as needed, and very flexible, so it is widely used in

Zero basic learning python _ list and Meta Group (course 10-13), python10-13 Today, I will go back and look at the list and metadata. Let's talk about the list. The list is actually the most frequently used data type in python. It is not only often used but also powerful, this is similar to the array in the C language, and the list can also be added, deleted, mod

The python language has been increasingly liked and used by program stakeholders in recent years, as it is not only easy to learn and master, but also has a wealth of third-party libraries and appropriate management tools; from the command line script to the GUI program, from B/S to C, from graphic technology to scientific computing, Software development to automated testing, from cloud computing to virtualization, all these areas have

Zeng Teacher's "Basic course of finite element Analysis" The third chapter has the derivation of two-dimensional rod element, and combines an example to analyze and solve the program based on MATLAB. But I feel the MATLAB code in the book is a bit wordy, and some of the implementation methods are more troublesome, such as already know the starting point and the end point coordinates, still need to give the unit local coordinates and the overall coordi
