10.7. glob — Unix 风格路径名模式扩展

源代码: 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.listdir() 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 '?'


返回匹配 pathname 的可能为空的路径名列表,路径名必须为包含一个路径描述的字符串。 pathname 可以是绝对路径 (如 /usr/src/Python-1.5/Makefile) 或相对路径 (如 ../../Tools/*/*.gif),并且可包含 shell 风格的通配符。 无效的符号链接可以包含在结果中 (与在 shell 中一样)。


返回一个 iterator,它会产生与 glob() 相同的结果,但不会实际地同时保存它们。

For example, consider a directory containing only the following files: 1.gif, 2.txt, and card.gif. 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')

如果目录包含以 . 打头的文件,它们默认将不会被匹配。 例如,考虑一个包含 card.gif.card.gif 的目录:

>>> import glob
>>> glob.glob('*.gif')
>>> glob.glob('.c*')
