Test your knowledge: glob and fnmatch patterns

Review

1. What does glob.glob() return when its pattern matches several entries?

   glob.glob() expands a pathname pattern and returns matching pathnames as strings.
2. What should a program do when glob results must be shown in a stable order?

   The order returned by glob depends on the filesystem; sort the results when order matters.
3. Which call enables ** to match across directory levels?

   The ** component is recursive only when recursive=True is supplied to glob.glob().
4. Why use glob.iglob() instead of glob.glob() for a large result set?

   iglob() yields the same kinds of matches through an iterator; it can avoid retaining the complete result list.
5. Which option allows glob wildcards to match hidden path components?

   include_hidden=True enables wildcard matching for hidden path components; it was added in Python 3.11.
6. Which function always uses case-sensitive matching?

   fnmatchcase() skips operating-system case normalization. fnmatch() may normalize case according to the operating system.
7. What is special about / to fnmatch patterns?

   fnmatch matches filename-like strings; path separators are not special. Use glob when the job is pathname expansion.
8. When a literal filename contains [ or *, which tool helps make a glob pattern match it literally?

   glob.escape() escapes wildcard metacharacters in a pathname for literal matching.
9. Which comparison is accurate?

   Path.glob() returns Path objects. glob returns strings, has module-specific options, and suppresses OSError raised during scanning.
