Analysis of Python Functions

Python was born in the hands of Guido. In fact, the first implementation was on a Mac machine. The special requirements of the Python language were rewritten in a more appropriate language, such as the graphic rendering module in 3D games, if the speed requirement is very high, you can use C ++ to rewrite it. The following describes the Python function.

Python is a very easy-to-use language. Many beginners of Java will be confused by Java CLASSPATH, it took more than half a day to figure out that it was because CLASSPATH made a mistake about its Hello World and it was impossible to run it. This problem won't occur in Python, and it can be used directly as long as it is installed.

Python is a scripting language that can run directly after being written, saving the trouble of compiling links. For beginners who need more hands-on practices, there is no chance of errors. In addition, Python also has an interactive mode. If it is a simple small program, the editor can be saved and can be run simply by clicking in. Python is a clear language.

Using indentation to express the nested relationship of a program is a kind of innovation. It upgrades the soft programming style of the past to a rigid syntax. There is no need to choose between different styles or dispute over different styles. Unlike Perl, Python does not have any obscure abbreviations and does not need to remember the meanings of various strange symbols. A program written in Python is easy to understand. This is the consensus of many people.

Python is an object-oriented language, but its object-oriented language does not emphasize concepts as C ++ does, but focuses more on practicality. The language is not complicated to reflect the complete support for the concept. The simplest way is to allow programmers to enjoy the benefits of object-oriented, which is one of the reasons why Python attracts many supporters like Java and C.

Python is a language with rich functions. It has a powerful basic class library and a large number of third-party extensions, so that Python programmers do not need to envy Java JDK. Python provides a rich set of basic functions for programmers, so that people do not need to write the program at the bottom layer. Speaking of this, people usually use a worry: The scripting language is usually slow. The speed of running the script language is indeed slower, but the speed of Python is much faster than people think.

Although Python is a scripting language, it can also be compiled, just like compiling a Java program, to compile a Python program into a special ByteCode, the execution is ByteCode, saving the analysis and interpretation of the program text, which naturally improves the speed. In Java programming, people advocate a method of Pure Java, except that everything in the virtual machine is written in Java, whether it is the basic data structure or graphical interface.

The SWING of Pure Java has become a nightmare for countless Java application developers. Python advocates practicality. Its overall environment is written in C. Many basic functions and extended modules are written in C/C ++. When executing this part of code, the speed is the speed of C. The startup speed of a common desktop program written in Python is not much different from that written in C.

In addition, through some third-party software packages, the source code written in Python can also be run in a JIT-like way, which can greatly improve the speed of running Python code, for different types of code, there will be a speed increase of 2 to 100 times.

Python is the most perfect combination of ease of use and speed in the languages I have seen. It achieves higher programming efficiency by losing a little bit of speed that is often negligible, this is why I chose Python. Focus on the problems you want to solve and select a proper language, so that you can focus on the problems you need to solve. Different Languages have different functions.

C and assembly are suitable for compiling system software. If they are used to compile enterprise applications, I am afraid few of them will be handy. I used to come across a guy who used to write database programs. Although the most basic functions have been completed, but to add a report preview or something, he can't cope with it. Smart programmers use suitable tools to complete their tasks. It is impossible to find a universal key.

Python's automatic garbage collection mechanism is a basic feature of advanced programming languages. Programmers generally do not have to worry about memory leaks when programming in languages with this function, when we use C/C ++ to write a program, this is one of the most important issues that require careful consideration but are prone to errors.

The data structure is an important part of the program composition. The linked list, tree, and diagram are much simpler in Python than they need to be carefully expressed when programming in C. In Python, the most basic data structures are arrays, sequences, and hash tables. It is very easy to use them to express various common data structures. Programming becomes interesting without defining pointers and allocating memory tasks.

CORBA is an advanced software architecture that is independent of a language-independent platform. C ++, Java, and other languages all have CORBA bindings, but compared with them, Python's CORBA bindings are much easier, because in the programmer's opinion, there is no difference in the use and implementation of a class of a CORBA and a class of Python functions.

Without the trouble of complicated architecture, it is also easy to write a CORBA program using Python. Good steel should be used in the cutting edge. If you want to complete as many tasks as possible with limited time, you must discard all kinds of irrelevant problems. Python just provides this method.
