Use Python to delete duplicate files in your computer! Its so simple!

In the life , We often encounter duplicate files in the computer .

In the case of fewer files , This kind of situation is relatively easy to handle , The worst thing is to manually compare and delete one by one ;

And when there are many duplicate files , It is difficult for us to guarantee that all duplicate documents will be deleted .

Leader Huang here has brought us a convenient method —— use Python To remove duplicate files

Practice time

Python Provide a built-in computer file management library os modular , We can use it to delete superfluous files .

When there are duplicate file names in a document , Our system will automatically rename our duplicate file names , For example, the following file “1” repeated 3 Time ：

So how do we delete files “1” What about duplicate files ？

We can use os Modular os.remove(path) function , Just specify path Parameters , That is, the path of the file , You can delete the file .

I need to remind you that , It must be the path containing the file name .

If it is not the path containing the file name , You're going to report a mistake , Because this is deleting the entire folder .

Code demonstration

Here we show you the code directly ：

import os # Load file management library
path = "D:\projects"
files = os.listdir(path) # os.listdir(path) List path The names of all files under the are combined with ” list “ Form return of
print(type(files)) # verification files The type of print(" route :{} The files owned under are {}".format(path, files)) # Print path All file names under
files_delete = files[0:2] # Find the file name you want to delete , Here we can also use input Function to specify the file I need to delete ！
print(files_delete) # Print the file name to delete
for file_name in files_delete:
file_path = os.path.join(path, file_name) # Application os.path.join(path, file_name) Concatenate file path and file name , Form a new path
os.remove(file_path) # Delete file
print(" After deleting duplicate files , path What are the file names under :", os.listdir(path))  #  Print the remaining files after deleting duplicate files 

Then go to the folder of the path we specified , Duplicate files are deleted ！

Function annotations in code ：

1. file_list = os.listdir(path): List the specified file path ( Parameters path) All files in , And return... As a list .
2. file_path = os.path.join(path, " file name ")： Concatenate file path and file name , Form a new path . such as ：os.path.join(path="D:\projects", "xiaobei.txt") The result is zero ："D\projects\xiaobei.txt"\
3. os.remove(path) Delete the specified path The name of the file .

summary

Students can try it on their own Python Remove duplicate files from your computer ！

Of course , Before practice , Study Python The basic knowledge of is very important .
