Python: search for a file in current directory and all it's parents -


is there inbuilt module search file in current directory, super-directories?

without module, i'll have list files in current directory, search file in question, , recursively move if file isn't present. there easier way this?

well not implemented, work

use listdir list of files/folders in current directory , in list search file.

if exists loop breaks if doesn't goes parent directory using os.path.dirname , listdir.

if cur_dir == '/' parent dir "/" returned "/" if cur_dir == parent_dir breaks loop

import os  file_name = "test.txt" #file searched cur_dir = os.getcwd() # dir search starts can replaced path  while true:     file_list = os.listdir(cur_dir)     parent_dir = os.path.dirname(cur_dir)     if file_name in file_list:         print "file exists in: ", cur_dir         break     else:         if cur_dir == parent_dir: #if dir root dir             print "file not found"             break         else:             cur_dir = parent_dir

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
