11.7. glob — Unix style pathname pattern expansion - Python 3.6.15 documentation 编辑
Source code: Lib/glob.py
The glob
module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell, although results are returned in arbitrary order. No tilde expansion is done, but *
, ?
, and character ranges expressed with []
will be correctly matched. This is done by using the os.scandir()
and fnmatch.fnmatch()
functions in concert, and not by actually invoking a subshell. Note that unlike fnmatch.fnmatch()
, glob
treats filenames beginning with a dot (.
) as special cases. (For tilde and shell variable expansion, use os.path.expanduser()
and os.path.expandvars()
.)
For a literal match, wrap the meta-characters in brackets. For example, '[?]'
matches the character '?'
.

module offers high-level path objects.
glob.
glob
(pathname, *, recursive=False)Return a possibly-empty list of path names that match pathname, which must be a string containing a path specification. pathname can be either absolute (like
/usr/src/Python-1.5/Makefile
) or relative (like../../Tools/*/*.gif
), and can contain shell-style wildcards. Broken symlinks are included in the results (as in the shell).If recursive is true, the pattern “
**
” will match any files and zero or more directories and subdirectories. If the pattern is followed by anos.sep
, only directories and subdirectories match.Note
Using the “
**
” pattern in large directory trees may consume an inordinate amount of time.Changed in version 3.5: Support for recursive globs using “
**
”.
glob.
iglob
(pathname, *, recursive=False)Return an iterator which yields the same values as
glob()
without actually storing them all simultaneously.
glob.
escape
(pathname)Escape all special characters (
'?'
,'*'
and'['
). This is useful if you want to match an arbitrary literal string that may have special characters in it. Special characters in drive/UNC sharepoints are not escaped, e.g. on Windowsescape('//?/c:/Quo vadis?.txt')
returns'//?/c:/Quo vadis[?].txt'
.New in version 3.4.
For example, consider a directory containing the following files: 1.gif
, 2.txt
, card.gif
and a subdirectory sub
which contains only the file 3.txt
. glob()
will produce the following results. Notice how any leading components of the path are preserved.
>>> import glob >>> glob.glob('./[0-9].*') ['./1.gif', './2.txt'] >>> glob.glob('*.gif') ['1.gif', 'card.gif'] >>> glob.glob('?.gif') ['1.gif'] >>> glob.glob('**/*.txt', recursive=True) ['2.txt', 'sub/3.txt'] >>> glob.glob('./**/', recursive=True) ['./', './sub/']
If the directory contains files starting with .
they won’t be matched by default. For example, consider a directory containing card.gif
and .card.gif
:
>>> import glob >>> glob.glob('*.gif') ['card.gif'] >>> glob.glob('.c*') ['.card.gif']
