Compiled Python Script Source Code | N/A | Executable Files |
The .PYC file extension is a compiled file format used to store data and instructions specifically for the Python programming language. It is of the type compiled program code and is a compressed version of a .PY (Python Script File). The .PYC files are created when a user compiles a .PY file, which then results in the generation of the .PYC version.
The .PYC files are important as they provide faster execution speeds compared to a standard .PY file. This is because Python compiles the code within the script to bytecode before executing it. This conversion process increases speed of execution and allows for efficient performance when the same script is being used multiple times. Furthermore, the bytecode produced can also be archived and moved to other locations to avoid repeated compilation.
Similar File Extensions
Other similar file extensions for compiled scripts include, but are not limited to, .C, .EXE, .COM, .OBJ, and DLL.
Security Considerations
It is important to note that, even though the actual source code is hidden inside a .PYC file, it can still be reverse-engineered using specific tools in order to view the source code. To learn more about security best practices related to .PYC files, users should consult with professional security organizations in their field.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PYC) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PYC extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PYC file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PYC extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PYC extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PYC file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PYC file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PYC file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PYC file) will be extended to the maximum.
It is also good to check
- if the .PYC file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
