Python background color and syntax highlighted topic Configuration
Anyone using python idle may not be able to tolerate the default white background and its syntax highlighting themes.
You are more inclined to use black backgrounds.
The following describes three theme configurations: Obsidian, Desert, and Tango.
Create a new config-highlight.cfg file under the. idlerc directory in the user directory and add the following content

Idlerc directory for the user directory:The following systems correspond to the location of the file: Under the Linux Series system path is (~ means user directory):~/.idlerc/ under Windows XP path is: C:/documents and settings/under Windows 7, the path is: C:/users/under Window, you can enter the following path directly in

There is no error stating that the configuration was successful.
Another is to put MinGW into the notepad++, very simple, in the "Run" menu to add 3 buttons on it:
Compile cmd /k ...\MinGW\bin\g++.exe -g -W -Wall -o$(CURRENT_DIRECTORY)\$(NAME_PART).exe$(FULL_CURRENT_PATH) PAUSE EXIT
Run cmd /k $(CURRENT_DIRECTORY)\$(NAME_PART).exe pause exit
Debug cmd /k ...\MinGW\bin\gdb.exe $(CURRENT_DIRECTORY)\$(NAME_PART).exe
In this way, after writing the code can

Grouping histograms
Sometimes we want to compare two different kinds of objects in the same data, we can use the grouping histogram. We use the Cabbage_exp dataset, which contains two different types of data

highlighted in the divisor can be implementedUsing this instruction. We must also add the results together for each element of the column, which we do using the accumulating version of the same struction.
As we are operating on the columns of the first matrix, and producing a column of results, reading and writing elements to and from memory is a linear operation, and requires no interleaving load or store instructions.Codefloating point
First, we will look at an implementation that multiplies
