PYC File - opening and understanding

Did your computer fail to open a PYC file? We explain what they are used for and recommend software that we know can open or otherwise handle your .PYC files.

What is a PYC file?

PYC (Python Compiled) file extension is often related to executable files that contain compiled source code written in the Python programming language. Python programming language is a dynamic, object-oriented language used for creating a variety of software. Python runs on Windows, Mac OS X, and Linux/Unix. It has been ported to Java and .NET virtual machines. It also runs on older platforms like OS/2 and Amiga.PYC files primarily contain Python bytecode. A bytecode is an instruction set executed by its designated software interpreter. Bytecode is the result of compiling source code written in a specific programming language. The virtual machine converts each bytecode into a specific machine instruction that the computer processor understands. Since Python instruction sets are bytecodes, they have to be coverted before it can be interpreted and finally executed. Keeping its accompanying .py files (it comes along with PYC files) can help speed up execution. With PYC and PY files saved, you don't have to recompile the instructions.

How to open PYC files

You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension PYC for different purposes.

While we have not verified the apps ourselves yet, our users have suggested 10 different PYC openers which you will find listed below.

Suggest another file format using extension PYC

While we know of one file format using the .PYC file extension, there may be more. It is widespread that different programs use files with the same file extension for very different types of data. Please let us know if you are aware of a different kind of .PYC file.
