# pyqver - query required Python version Greg Hewgill [http://hewgill.com](http://hewgill.com) ## INTRODUCTION This script attempts to identify the minimum version of Python that is required to execute a particular source file. When developing Python scripts for distribution, it is desirable to identify which minimum version of the Python interpreter is required. `pyqver` attempts to answer this question using a simplistic analysis of the output of the Python compiler. When run without the `-v` argument, sources are listed along with the minimum version of Python required. When run with the `-v` option, each version is listed along with the reasons why that version is required. For example, for the `pyqver2.py` script itself: pyqver2.py 2.3 platform This means that `pyqver2.py` uses the `platform` module, which is a 2.3 feature. The `pyqver2.py` script is specific to Python 2.x, and `pyqver3.py` is specific to Python 3.x. This script was inspired by the following question on Stack Overflow: [Tool to determine what lowest version of Python required?][1] [1]: http://stackoverflow.com/questions/804538/tool-to-determine-what-lowest-version-of-python-required ## REQUIREMENTS This script requires at least Python 2.3. ## USAGE Usage: pyqver[23].py [options] source ... Report minimum Python version required to run given source files. -m x.y or --min-version x.y (default M.N) report version triggers at or above version x.y in verbose mode -l or --lint print a lint style report showing each offending line -v or --verbose print more detailed report of version triggers for each version `M.N` is the default minimum version depending on whether `pyqver2.py` or `pyqver3.py` is run. ## BUGS There are currently a few features which are not detected. For example, the 2.6 syntax try: # ... except Exception as x: # ... is not detected because the output of the `compiler` module is the same for both the old and the new syntax. The `TODO` file has a few notes of things to do.
