Maybe you have Explorer configured to hide file extensions, and you have one file named "filename.JPG" and another named "filename.jpg.JPG". On a related note, the new support for case-sensitive directories in Windows 10 can lead to an issue when running commands. Shells use the PATHEXT environment variable to supply a list of default extensions when searching PATH for a command. These are usually upper case, so if we run "script" and it searches for "script.PY", it won't find "script.py" in a case-sensitive directory. The same applies to Python's shutil.which(). Regarding this topic, glob.py and fnmatch.py are unreliable in Windows for case-sensitive NTFS directories. Sometimes they rely on regular expressions and os.path.normcase (for ntpath.normcase, this replaces slash with backslash and converts to lowercase), and sometimes they rely on stat-based functions such as os.path.lexists, which will be case sensitive. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
