PYC Version Identification

Tool Introduction

This tool aims to help users identify the Python version of .pyc files online. A .pyc file is a Python compiled bytecode file, and its header contains a magic number that identifies the Python interpreter version that compiled it. Understanding the specific version of a .pyc file is crucial for Python project migration, compatibility checks, and debugging code in different Python environments. This tool accurately identifies the corresponding Python version by parsing the header information of the .pyc file, facilitating quick judgment and troubleshooting for developers.

How to Use

1. Drag your .pyc file to the designated area, or click the upload button to select a file.
2. The system will automatically parse the uploaded .pyc file, or do so after you click the "Identify" button.
3. After parsing is complete, the tool will display the Python version information corresponding to the .pyc file.

Input Parameter Format:

• Please upload a valid Python compiled bytecode file, i.e., a file with the .pyc extension.
• The file content must be in the standard .pyc file format, containing the correct magic number header information.

Output Result Format:

• The tool will directly display the Python version corresponding to the .pyc file, for example: Python 3.8.10, Python 2.7.16, and may include its internal magic number.

Frequently Asked Questions

• Q: What types of files does this tool support identifying?
• A: This tool is specifically designed to identify standard format .pyc files (Python compiled bytecode files).
• Q: What information will the output provide?
• A: The output will clearly display the Python version corresponding to the .pyc file (e.g., Python 3.8.5), and may include its internal magic number for advanced users' reference.
• Q: What if the uploaded .pyc file fails to be identified?
• A: Please check if your .pyc file is complete and undamaged. Sometimes, non-standard or truncated .pyc files may not be parsed correctly. Ensure that the uploaded file is indeed a bytecode file compiled by Python.
• Q: Does it support identifying .pyo or .pyw files?
• A: This tool primarily targets .pyc files. .pyo files are optimized bytecode files, and their header structure is similar to .pyc, so they can usually be identified. .pyw files are Python scripts for Windows, not bytecode files, and are not supported for identification.

Notes

• Please ensure that you upload a complete and undamaged .pyc file; damaged or incorrectly formatted files may lead to identification failure.
• This tool only determines the Python version by parsing the magic number in the .pyc file header; it does not involve deep parsing of file content or code execution, so please use it with confidence.
• Due to Python version iterations, there may be subtle differences in .pyc file formats across different versions. This tool will try its best to cover the identification of mainstream Python versions.
• When uploading files, please pay attention to protecting personal privacy and data security, and avoid uploading .pyc files containing sensitive information.
