python glob issues with directory with [] in name

问题

I am using glob to find all *.shp files within a directory, but the directory name contains '[]' and that is causing glob to fail. Any workarounds for this?

My code is:

glob.glob(sub_dir+os.sep+'soilmu_a_*.shp')

where sub_dir is:

'C:\\Users\\oh\\wss_SSA_OH001_soildb_OH_2003_[2013-12-19]\\spatial\\'

The error message I get is:

*** error: bad character range

回答1:

As suggested in the manual page, you can modify your pattern and wrap the offending meta characters. Change [ to [[] and ] to []] (single character ranges corresponding to the meta character).

For instance:

pattern = sub_dir + os.se p +'soilmu_a_*.shp'
pattern = pattern.replace('[','[[]').replace(']','[]]')
glob.glob(pattern)

Yes, glob failed to find subdirectories when the parent directory path had [] in it, and I got NO error message! I found the problem by chance. I could wish that I had gotten an error message.

I switched to os.listdir to get the subdirectories, and since I needed the full path to the subdirectories, I had to paste that back in:

subdirs = [d for d in os.listdir(current_full_path) if os.path.isdir(current_full_path + '/' + d)]
for subdir in subdirs:
    subdir_full_path = current_full_path + '/' + subdir

@isedev is right about the character range but double replacement is NOT a sensible thing to do.

import re
ptn = re.sub('([\[\]])','[\\1]',ptn)

str.translate() should also work
