Extract files with a specific extension in a folder using Python

Extract files with a specific extension in a folder using Python
 

 

 

I don't know when the network is idle and useless. I hung up a Linux video tutorial, which contains many folders and many irrelevant files. This is simply intolerable for people who do not have to collect junk files. So I planned to extract them one by one manually and return them to a folder. There are too many helpless files, and there is really no spare time to extract them one by one. So I was planning to write a VC program. During the winter vacation at home, I suddenly lost my interest in the many windows APIs and a bunch of Functional Descriptions in English. It is true that you are too lazy to study independently.

In the past few days, I have learned the boost library and found a font written for python, which has aroused my desire for python for the semester, I mainly want to see the advantages of combining these two languages. Google once said that python core programming is good, but the quality of translation is not very good. I remember seeing it on a blog of Daniel that the translation quality is poor. I 'd rather not read it than read the original version. So I ran to the Amazon website and found a five-star book, <beginning Python using Python 2.6 and Python 3.1-James W. payne>, print it out and start my python journey.

 

Fortunately, I saw a lot in msdn before, and I was barely able to get through English. What do I fear when I added the powerful Google translation. After reading the basic syntax in one breath, I think it is strange that the syntax is less than 200 pages, and the basic types, functions, exceptions, classes, and OOP can be completed even if there are less than 200 pages. This is a big gap between C ++ and me. The C ++ syntax can really torture you. Later, I borrowed the core Python programming and found that the syntax over there was much more detailed.

So the book has been on the verge of battles over the past few days.

 

After talking about that, let's just return to the topic. This program is actually very simple, without regular expressions (it is really a good thing, boost makes C ++ also supports regular expressions, haha, but I have not started learning, it is also very easy. No, read the program.

I don't need to comment it out. It's quite simple.

I started to learn python. This code must be ugly and I will try again later.
