9 | # |
---|
10 | # November 2015 - Leopold Haimberger (University of Vienna): |
---|
11 | # - modified method list_files to work with glob instead of listdir |
---|
12 | # - added pattern search in method list_files |
---|
13 | # |
---|
14 | # February 2018 - Anne Philipp (University of Vienna): |
---|
15 | # - applied PEP8 style guide |
---|
16 | # - added documentation |
---|
17 | # - optimisation of method list_files since it didn't work correctly |
---|
18 | # for sub directories |
---|
19 | # - additional speed up of method list_files |
---|
20 | # - modified the class so that it is initiated with a pattern instead |
---|
21 | # of suffixes. Gives more precision in selection of files. |

31 | # expression pattern for this instance and can produce a list of Files |
---|
32 | # from the given file pattern. These files can be deleted. |
