PS： During my testing ,
python3.9
Version does not support decompilation , I haven't found any problems with other applications for the time being , Can be decompiled successfully .
A： Write me a program , What I want to achieve
B： Well done. , Here you are.
A： The operation failed ...
B： Let me see
B： You have not installed xxx\xxx\xxx modular , Just install it
A： So much trouble ？ This is the intranet , Download the old trouble
B： I don't care , I realized it for you
A： Your skill is not good ~~~
B：？？？
A： wow , Your code is so awesome , Just run it directly ;
B： Oh dear , Just so so ;
A： How did you achieve it , Send me the source code and let me have a look ;
B： What source code do you want , It's easy , It's not that I won't show you , I lost my code ;
A：~~~
In both cases , I don't know if you have ever met , If any , After reading this article , If you encounter such a problem again , It's done in minutes .
python
Packaged into executable files on various platforms , In fact, it uses pyinstaller
modular ;
He can make you python
The code is packaged into various types of , For example, running in windows
Upper .exe
Format file , Or run on linux
The executable on ; What's the advantage of doing this ？
We all know , Write python
Many modules need to be installed in the code , Then the late running servers often lack modules , But we go through pyinstaller
After the module is packaged , You can run on a machine that does not have these modules installed , Let's see how to operate it .
pip install pyinstaller
pythonI want to pack it up in
windows
Running down.exe
Word of the file , It's justwindows
Packaging under the platform ;linux
also ; In other words, what platform do you want to execute in the later stage , Then you need to package on what platform ;
For example, our source code is as follows ：
#!/usr/bin/python
#coding:utf-8
from datetime import datetime
now_date = datetime.now()
print(' The current time is ：' + str(now_date))
Packing command ：

Because I am in windows
Running on the platform , So it's just one ceshi.exe
file , If you want to make the following program in linux
Run on the platform , Then you need to be in linux
Package on the platform ;
stay windows
Packaged on the platform python
Code , Double click to run ;
stay linux
Packaged on the platform python
Code , Only use ./
To execute , for example ：
./ceshi
If we get python
Packaged code , Want to see the source code , Or the person who provided the package left , No source code , How do we look at the source code in this case ？ And look down ;
For example, what we get is what we got after packaging in the previous step ceshi.exe
file , How to see the source code ？
You need to use a script here pyinstxtractor.py

Use imhex
Software , This software is a hexadecimal compiler , The software installation is simple , Just go to the next step in turn , No special operation is required ; Open after installation struct.pyc
file , Here's the picture ：
We need to record the value of the first line , Here's the picture ：
Then close the file , Open another ceshi.pyc
file , Here's the picture ：
Modify the values of the first row and struct.pyc
The first line of the file has the same value , Here's the picture ：
Then save the contents of the file ;
Here we need to use another module , namely uncompyle6
, Get the software from the end of the question , After unpacking, use the following command to install ;
PS C:\Users\22768\Desktop\python-uncompyle6-master> python .\setup.py install
After installation , We go back to having ceshi.pyc
Under the directory of this file ;
PS C:\Users\22768\Desktop\yunwei_ceshi\dist\ceshi.exe_extracted> uncompyle6 .\ceshi.pyc > nihao.txt
This nihao.txt
Is our source code .
A script is used in this article pyinstxtractor.py

package uncompyle6
