Example of using glob to compile a list of filepaths

glob_example.py

from glob import glob

filepaths = glob('*txt')
for filepath in filepaths:
    f = open(filepath,'U')
    # tip: always open files for reading with mode 'U' rather
    # than mode 'r'
    ## Do whatever with the open file
    f.close()

# if files of interest are all in subdirectories of the 
# current working directory, something like this would work

filepaths = glob('*/*txt')
for filepath in filepaths:
    f = open(filepath,'U')
    # tip: always open files for reading with mode 'U' rather
    # than mode 'r'
    ## Do whatever with the open file
    f.close()
