Problem Python 3 is not backward compatible with Python 2 User's project Python version: 2.x Reuse code Python 2 features User's project Python version: 3.x Reuse 1
Problem Python 3 is not backward compatible with Python 2 User's project Python version: 2.x Reuse code Python 2 features User's project Python version: 3.x Reuse May affect users of Q&A sites such as Stack Overflow (SO) 2
Empirical Study Investigating how common are SO Python code snippets with version compatibility issues About 10% of snippets have version compatibility issues in the top answers to questions Only about 17% of snippets interpretable only by Python 2 or only by Python 3 are tagged with the Python version 3
Empirical Study Investigating how common are SO Python code snippets with version compatibility issues A tool needs to be provided for users to detect the Python version of the Python code snippets on SO 4
PyVerDetector A Chrome extension that helps SO users address the version compatibility issue of Python code snippets SO Page Code Snippet Drop-down menu Select Python Version Message Areas 5
PyVerDetector Fetching the code snippet from SO Displaying the results Frontend 6
PyVerDetector Statically analyzing the given code snippet across multiple Python versions Backend 7
Usage Scenarios 1.Displaying the latest version as default 2.Accurate display of results for selected versions 9
Usage Scenarios 1.Displaying the latest version as default For all Python code snippets on the page 10
Usage Scenarios 2. Accurate display of results for selected versions Before selecting a version
After selecting a version Usage Scenarios def f(a, b, /, c, d, *, e, f): 2. Accurate display of results for selected versions Before selecting a version Positional-only parameters After selecting a version At line 4 syntax error, unexpected / 12
After selecting a version Usage Scenarios def f(a, b, /, c, d, *, e, f): 2. Accurate display of results for selected versions Before selecting a version Positional-only parameters After selecting a version Other compatible Python versions 13
