我如何在Python中获得给定目录中的所有文件(和目录)的列表?
当前回答
我写了一个很长的版本,包含了我可能需要的所有选项:http://sam.nipl.net/code/python/find.py
我想它也适合这里:
#!/usr/bin/env python
import os
import sys
def ls(dir, hidden=False, relative=True):
nodes = []
for nm in os.listdir(dir):
if not hidden and nm.startswith('.'):
continue
if not relative:
nm = os.path.join(dir, nm)
nodes.append(nm)
nodes.sort()
return nodes
def find(root, files=True, dirs=False, hidden=False, relative=True, topdown=True):
root = os.path.join(root, '') # add slash if not there
for parent, ldirs, lfiles in os.walk(root, topdown=topdown):
if relative:
parent = parent[len(root):]
if dirs and parent:
yield os.path.join(parent, '')
if not hidden:
lfiles = [nm for nm in lfiles if not nm.startswith('.')]
ldirs[:] = [nm for nm in ldirs if not nm.startswith('.')] # in place
if files:
lfiles.sort()
for nm in lfiles:
nm = os.path.join(parent, nm)
yield nm
def test(root):
print "* directory listing, with hidden files:"
print ls(root, hidden=True)
print
print "* recursive listing, with dirs, but no hidden files:"
for f in find(root, dirs=True):
print f
print
if __name__ == "__main__":
test(*sys.argv[1:])

你可以使用
os.listdir(path)
参考和更多的操作系统函数看这里:

path = '.'
for dirname, dirnames, filenames in os.walk(path):
# print path to all filenames with extension py.
for filename in filenames:
fname_path = os.path.join(dirname, filename)
fext = os.path.splitext(fname_path)[1]
if fext == '.py':
print fname_path
else:
continue
#import modules
import os
_CURRENT_DIR = '.'
def rec_tree_traverse(curr_dir, indent):
"recurcive function to traverse the directory"
#print "[traverse_tree]"
try :
dfList = [os.path.join(curr_dir, f_or_d) for f_or_d in os.listdir(curr_dir)]
except:
print "wrong path name/directory name"
return
for file_or_dir in dfList:
if os.path.isdir(file_or_dir):
#print "dir : ",
print indent, file_or_dir,"\\"
rec_tree_traverse(file_or_dir, indent*2)
if os.path.isfile(file_or_dir):
#print "file : ",
print indent, file_or_dir
#end if for loop
#end of traverse_tree()
def main():
base_dir = _CURRENT_DIR
rec_tree_traverse(base_dir," ")
raw_input("enter any key to exit....")
#end of main()
if __name__ == '__main__':
main()
简单的方法:
list_output_files = [os.getcwd()+"\\"+f for f in os.listdir(os.getcwd())]
import os
for filename in os.listdir("C:\\temp"):
print filename
