python read subfolder
You can us os.walk() to recursively iterate through a directory and all its subdirectories: for root, dirs, files in os.walk(path): for name in files: if name.endswith((".html", ".htm")): # whatever. To build a list of these names, you,Take a look at the Packages documentation (Section 6.4) here: http://docs.python.org/tutorial/modules.html. In short, you need to put a blank file named __init__.py. in the "lib" directory. ,Do you mean immediate subdirectories, or every directory right down the tree? Either way, you could use os.walk to do this: os.walk(directory). will yield a tuple for each subdirectory. Ths first entry in the 3-tuple is a directory name, so [x[0] for x in, Looks like you are doing os.walk() loop incorrectly. There is no need for nested dir loop. Please refer to Python manual for the correct example: https://docs.python.org/2/library/os.html?highlight=walk#os.walk for root, dirs, files in os.walk('pytho, Use os.path.relpath() . This is exactly its intended use. import os rootDir = "myfolder" fileSet = set() for dir_, _, files in os.walk(rootDir): for fileName in files: relDir = os.path.relpath(dir_, rootDir) relFile = os.path.join(relDir, fileN,So the equivalent to os.path.join would be: pathlib.PurePath(path, name). The advantage of pathlib is that you can use a variety of useful methods on paths. If you use the concrete Path variant you can also do actual OS calls through them, like chanding i, Use os.walk(). The following will output a list of all files within the subdirectories of "dir". The results can be manipulated to suit you needs: import os def list_files(dir): r = [] subdirs = [x[0] for x in os.walk(dir)] for subdir in subdir,If you are sure the file you want is in a subdirectory beneath where the script is actually located, you can use __file__ to help you out here. ... import os def readFile(filename): filehandle = open(filename) print filehandle.read() filehandle.close() fi,You need to use absolute paths, your file variable is just a local filename without a directory path. The root variable is that path: with open('output.txt','w') as fout: for root, subFolders, files in os.walk(rootdir): if 'data.txt, In your example you seem to be triggering a Permission Denied IOError because you are trying to call open() directly on a folder. Also, you may get the name(s) of system files (like NTUSER.DAT) returned by os.listdir(), and you can't rely on being ab
