If the position of the character isn t important  that is for example to exclude manifests files  wherever it is found    with glob and re - regular expression operations  you can use  import glob import re for file in glob glob    txt        if re match r          file           continue     else          print file   Or with in a more elegant way - list comprehension filtered    f for f in glob glob    txt   if not re match r          f    for mach in filtered      print mach

More generally  to exclude files that don t comply with some shell regexp  you could use module fnmatch       import fnmatch  file list   glob  somepath       for ind  ii in enumerate file list       if not fnmatch fnmatch ii   bash regexp with exclude            file list pop ind    The above will first generate a list from a given path and next pop out the files that won t satisfy the regular expression with the desired constraint

You can use the below method     Get all the files allFiles   glob glob        Files starting with eph ephFiles   glob glob  eph      Files which doesnt start with eph noephFiles      for file in allFiles      if file not in ephFiles          noephFiles append file    noepchFiles has all the file which doesnt start with eph   Thank you

Late to the game but you could alternatively just apply a python filter to the result of a glob   files   glob iglob  your path here   files i care about   filter lambda x  not x startswith  eph    files    or replacing the lambda with an appropriate regex search  etc     EDIT  I just realized that if you re using full paths the startswith won t work  so you d need a regex   In  10   a Out 10      some path foo    some path bar    some path eph thing    In  11   filter lambda x  not re search   eph   x   a  Out 11      some path foo    some path bar

The pattern rules for glob are not regular expressions  Instead  they follow standard Unix path expansion rules  There are only a few special characters  two different wild-cards  and character ranges are supported  from pymotw  glob     Filename pattern matching   So you can exclude some files with patterns  For example to exclude manifests files  files starting with    with glob  you can use  files   glob glob  files path

You can t exclude patterns with the glob function  globs only allow for inclusion patterns  Globbing syntax is very limited  even a       character class must match a character  so it is an inclusion pattern for every character that is not in the class    You ll have to do your own filtering  a list comprehension usually works nicely here   files    fn for fn in glob  somepath   txt             if not os path basename fn  startswith  eph

Compare with glob  I recommend pathlib  filter one pattern is very simple   from pathlib import Path  p   Path YOUR PATH  filtered    x for x in p glob         if not x name startswith  eph      and if you want to filter more complex pattern  you can define a function to do that  just like   def not in pattern x       return  not x name startswith  eph    and not x name startswith  epi     filtered    x for x in p glob         if not in pattern x     use that code  you can filter all files that start with eph or start with epi

How about skipping the particular file while iterating over all the files in the folder  Below code would skip all excel files that start with  eph   import glob import re for file in glob glob    xlsx        if re match  eph    xlsx  file           continue     else           do your stuff here         print file    This way you can use more complex regex patterns to include exclude a particular set of files in a folder

As mentioned by the accepted answer  you can t exclude patterns with glob  so the following is a method to filter your glob result   The accepted answer is probably the best pythonic way to do things but if you think list comprehensions look a bit ugly and want to make your code maximally numpythonic anyway  like I did  then you can do this  but note that this is probably less efficient than the list comprehension method     import glob  data files   glob glob  path to files   fits    light files   np setdiff1d  data files  glob glob   BIAS     light files   np setdiff1d light files  glob glob   FLAT        In my case  I had some image frames  bias frames  and flat frames all in one directory and I just wanted the image frames
