glob
--- Unix style pathname pattern expansion¶
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()
.)
对于字面值匹配,请将原字符用方括号括起来。 例如,'[?]'
将匹配字符 '?'
。

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). Whether or not the results are sorted depends on the file system.If recursive is true, the pattern "
**
" will match any files and zero or more directories, subdirectories and symbolic links to directories. If the pattern is followed by anos.sep
oros.altsep
then files will not match.Raises an auditing event

(pathname, *, recursive=False)¶ Return an iterator which yields the same values as
glob()
without actually storing them all simultaneously.Raises an auditing event

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'

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']
