Analysis of the cmp comparison principle of Python built-in comparison functions
Cmp (x, y): compares two objects. if the former is smaller than the latter,-1 is returned. if the former is equal, 0 is returned. if the former is greater than the
Comparison principle of CMP comparison function in Python
CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1.
Comparison principle of CMP comparison function in Python
EJB has two main types: BMP (bean managed persistence) and CMP (container managed persistence), which have their own advantages and disadvantages.
BMP is used to call database JDBC in bean. That is to say, in your entity bean, SQL statements such as
CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1.
Comparison principle of CMP comparison function in Python
The CMP functions of Python can be compared between the same
CMP is a comparison command. The CMP function is equivalent to a subtraction command. It does not save the result, but only affects the corresponding flag. Other commands identify these affected tags to learn the comparison results.

Python development [Notes]: sort Sorting Algorithm (cmp, key, reverse), pythoncmpSort
The sorting function is often used in the program. Python provides the sort and sorted functions, one in-situ sorting and one Returning New results after sorting.

Python function-cmp (x, y) today I will share a very useful and simple function named cmp in python. as you may have guessed in spelling, this is a comparison function, yes, it only returns three values, positive, 0, and negative. let's take a look:
After reading the cracking tutorial, we all know that "test" and "CMP" are the key, but I have never been clear about how they are compared. Finally, I made up my mind to find a lot of information and work with everyone to figure them out.
First,
Requirement: There is a structure array of student information, including class, score, age, and other information. A student's class is now required to be sorted based on the primary keyword. If the class is the same, it is sorted by the score,
0x01 Jump InstructionIn general, there are two kinds of JUMP commands in x86:1. Arithmetic jumps, such as JZ (jump if zero), JC (Carry), JNC (jumping if not carry), etc.2. Compare Jumps: Like JE (jump if equal), JB (jumping if below), JAE (if above
