Reading all files in all directories [duplicate]
Python doesn't support wildcards directly in filenames to the open() call. You'll need to use the glob module instead to load files from a single level of subdirectories, or use os.walk() to walk an arbitrary directory structure.
Opening all text files in all subdirectories, one level deep:
import globfor filename in glob.iglob(os.path.join('Test', '*', '*.txt')): with open(filename) as f: # one file open, handle it, next loop will present you with a new file.Opening all text files in an arbitrary nesting of directories:
import osimport fnmatchfor dirpath, dirs, files in os.walk('Test'): for filename in fnmatch.filter(files, '*.txt'): with open(os.path.join(dirpath, filename)): # one file open, handle it, next loop will present you with a new file.
