In the process of burning the program, you need to synthesize multiple binary bin files, and to specify the data segment address offset, the address between data segments to fill the default value of 0xFF. Because you don't want to do it manually, you can generate the merged bin file directly from the make command by adding a call to the Python script command in makefile to implement the bin file
, and the merge code is as follows z = {**x, **y} A line of code that is duly completed. Since many people are still using python2, there is a more elegant way for python2 and python3.0-python3.4, but two lines of code are required. z = x.copy () z.update (y) The above method, Y will overwrite the contents of x, so the final result is b=3. How to do a line without using python3.5 If you are not using Python
When you use Python or Django to write some gadget applications, you may encounter the case of merging multiple lists into a list. Purely from a technical point of view, it is not difficult to deal with, can think of a lot of ways, but I think there is a very simple and efficient method is I have not noticed before. That is to use the chain method to merge

In-depth analysis of multiple inheritance issues of Python classes, and in-depth analysis of python Body First, you must note that Python classes are classified into classic classes and new classes.The classic class is something before python2.2, but it is still compatible with Pyt
The case of merging multiple lists into a list is encountered. Use the chain method to merge multiple lists. It can also be used to merge Django's QuerySet.1. Python uses chain to merge multip

Yesterday, I had a long struggle with the multiple inheritance of the Python class. after consulting a lot of experts, I fully understood it. now I have sorted out the features of the class for future reference, you can also give reference to the following body for those who need it. First, you must note that Python classes are classified into classic classes an
The MRO method is the resolution order, which is mainly used to determine the path (from which class) of the property on multiple inheritance. In the python2.2 version, the basic idea of the algorithm is to compile a list, including the searched class, based on the inheritance structure of each ancestor class, to delete duplicates by policy. However, in the maintenance of monotonicity has failed (sequential save), so from the 2.3 version, the use of
, the code is a lot more concise and clear all of a sudden! Because the file in Python is a iterable object, it can be directly iterated by for. But there is a problem where the for-in can only iterate one sequence at a time. In this case, you can only read a single line from one file at a time, and then do some processing. But if you want to read a row from each of the two files each time, and then do some processing, such as text comparison, can y
Body The first thing to note is that the Python classes are divided into classic classes and modern classesThe classic class is something before python2.2, but in 2.7 it's still compatible, but in the 3 version, it only admits the new class.New classes can be used in versions after python2.2 The difference between a classic class and a new class is: The classic class is not derived from a base class by default, and the new class is derived from the b
MRO is method resolution order, which is used primarily to determine the path of a property (from which class) when multiple inheritance occurs. In the python2.2 version, the basic idea of the algorithm is to compile a list based on the inheritance structure of each ancestor class, including the search class, and delete the duplicates by policy. However, the maintenance monotonicity has failed (sequential saving), so from the 2.3 version, a new algor

OK, what if I convert the PDF document to another picture format? I recommend that you do this with Adobe acrobat X Pro software under Windowns, as shown in the following two figure.
