Python first,
1. Introduction to python

 

As currently the most popular Programming Language python, most programmers are learning python, and our bank is also organizing the python language and training every week. After listening to the Second Basic Course, I slowly liked this language. Why are everyone learning python? If you want to like anything, it must have its advantages. First, it is open-source software, and everything is free of charge. Python is an object-oriented language. What is an explanatory language?

I understand that C is like a manual vehicle (compiled language), java and python (interpreted language) are like automatic vehicles. The fastest-running cars are all manual files, but for non-good people, automatic files are faster.

When the C program runs, it is directly compiled into a machine code. The python code is translated into a byte code in python itself and then converted into a machine code, but python is also the closest to the C language, because python directly calls C in many places.

The python language features simplicity and elegance, easy to understand code, and as few code as possible. Python provides a complete base code library, including networks, files, databases, and texts. In addition to built-in libraries, there are also a large number of third-party libraries. Therefore, for python development, many functions do not need to be written from scratch and can be directly used as ready-made.

Python can be used in automation, crawler, and big data, but big data is mostly used in Java now. I personally think it is the first-mover. After all, Java has been so long, there are also many enterprise maintenance tools. Python is slower than other languages, but this factor does not exist in big data. I heard that python is slower than other languages because of the internal interpreter of python, if you erase this big data in big data and generate an interpreter, python is no longer slower than other languages. I believe the python language will become more and more perfect. Currently, python3 and python2 are not compatible.
