对于Python 2

#!/bin/python2

import os

def scan_dir(path):
    print map(os.path.abspath, os.listdir(pwd))

对于Python 3

对于filter和map，你需要用list()来包装它们

#!/bin/python3

import os

def scan_dir(path):
    print(list(map(os.path.abspath, os.listdir(pwd))))

现在的建议是用生成器表达式或列表推导式替换map和filter的使用:

#!/bin/python

import os

def scan_dir(path):
    print([os.path.abspath(f) for f in os.listdir(path)])

对于Python 2

#!/bin/python2

import os

def scan_dir(path):
    print map(os.path.abspath, os.listdir(pwd))

对于Python 3

对于filter和map，你需要用list()来包装它们

#!/bin/python3

import os

def scan_dir(path):
    print(list(map(os.path.abspath, os.listdir(pwd))))

#!/bin/python

import os

def scan_dir(path):
    print([os.path.abspath(f) for f in os.listdir(path)])

如果我觉得我会把这个扔进去。简单和肮脏的方式进行通配符搜索。

import re
import os

[a for a in os.listdir(".") if re.search("^.*\.py$",a)]

#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()

你可以使用

os.listdir(path)
