Most people don't use pathlib, and that's kind of sad, since it tries to
mitigate the kinds of questions you just asked. Kudos for trying.
For your example, when you define inp as a string, it needs to be a raw
string because otherwise Python will interpret the backslash sequences.
\t means tab, which is why the the results look mangled.
inp = "c:\test\drive\this"
If you're going to use pathlib, then may as well use the / operator for

[Tutor] path
A user has to type a path in the commandline on Win 10, so just a
string. This has to become a path / directory in the file system. Later
in the process subdirectories and files are 'appended' by the script. In
these files there are also paths, derived from the input path and they
have to use forward slashes. The tool that uses these files requires that.
# create structure:
# /---fullpath <-- input() cmd

Have a read of a graph theory textbook. Also, wikipedia has an article on
finding the shortest path through a graph:
https://en.wikipedia.org/wiki/Shortest_path_problem
which references several algorithms.
You could pick one (eg Dijkstra's algorithm) and try to implement it. For a
graph this small you could try your own and do something rather brute force; in
larger graphs efficiency becomes very important.
You will need to express the graph as a data structure in your code, with a
data structure that expresses which nodes connect to each other node. Typically
this often includes weights for the edges and a direction, but your graph has
no weights (cost of traversing a particular edge) and is undirected (you can
traverse an edge in either direction). It is also "simply connected" - there
are no loops. All these things make your task simpler.
You can express a graph as a direcionary with keys being your node numbers
(i.e. 1, 2, 3 etc) and the values being a list of the other nodes to which each
connects. Eg:
graph = {
1: [2],
2: [1, 3],
3: [2, 4],
4: [3],
5: [7, 6],
6: [5, 8],
7: [5],
8: [6]
}
The you need to write code that starts somewhere (4 in your example) and moves
to other nodes until it reaches the target node (8 in your example). You can
see which other nodes are reachable your current from the dictionary above. You
need to keep some kind of record of which nodes you have visted (i.e. that is
the path).
See if that gets you started. For debugging, make your program print out what
node it is at as it traverses the graph - that will be helpful to you in
figuring out what is working and what is not.

While Martin's solution is certainly more robust it may also be instructive

edges = [

There is no picture, don't know if you forgot to attach, or if it got stripped by the mailing list software (the latter does happen, although some seem to get through).

When you say unsuccessfully what do you mean?

For that you need to expose it outside the
function, the best way to do that is to return
it as a value, which you comment suggests you
want to do. But the only return is commented out,
so you need to tidy that up.
But personally I think your function is trying to do
too much. You should simplify it to only return the
files and have another function that returns the path.
Functions that try to do too many things (ie more
than one) are notoriously difficult to debug.

I'll take your word for it.

Return the value (assuming it is the right value)
and in part two assign the return from the
function to a variable.
For my analysis below I've removed all the flag
nonsense which is just cluttering things up for
now and gone with the ENDS_WITH option as
default

You could simplify that by putting the selectedFiles
line before the selectedPath line and use selectedFiles
inside the comprehension.

It would probably be better to check if they were empty
before putting them in. Since you use the endswith() test
I'm thinking there should never be any empty ones in
this scenario anyway?

Here is the missing return statement but it's not returning
what you said you wanted, ie str7

It might be wise to print the string itself to check
you have what you want, I'm not sure you do... But
I'm not really sure what you want since your code
logic is confusing me a bit here.
> str2 = str1.replace(" ", "") #remove white spaces
So why did you add it above? Why not just use an empty
string in the join?
However, more seriously, what affect does this have
on any paths/filenames that you found with spaces
in them? Is that really what you want?
> print 'str2 is', str2
> str3 = str2[13:16] #extract rgeistration
> print 'str3 is registration:', str3
I'll assume this is right since I've no idea what
format you think your filenames have. However, in general,
relying on fixed positions within a string is not a good
idea. This might be a valid case for using a regex which
can more flexibly match your pattern. But for now just
stick with the simple fixed values...
> str4 = 'FLDAT'
> print 'str4 is: ', str4
> str5 = str3.__add__(str4)
You shouldn't really call the dunder methods directly you
should use the + operator:
str5 = str3 + str4
Or, in this case, save a variable and use the literal:
str5 = str3 + 'FLDAT'
> print 'str 5 is: ',str5
> str6 = 'H://'
> print 'str6 is: ', str5
Did you really mean that? You've already printed str5.
And do you really need a double slash after the
drive letter? That's usually only needed if using
backslashes ('H:\\').
> str7 = str6.__add__(str5)
Again you could just use the literals:
str7 = 'H://' + str3 = 'FLDAT'
> print 'str7 is: ', str7
>
> fetchFiles('H://','ENDS_WITH','.FLD')
No assignment of any return value here

This assigns the literal string 'str7' is that what you want?
You cannot access the variable str7 that was inside the function.
It was a local variable and will have been destroyed by now.

[Tutor] path string
Dear Tutor.
I am trying to create unsuccessfully source path as a string 'str7' in part_1
of the code below, to be used in part_2 of the code.
When I define the source path explicitly in part_2 of the code (#sourcePath =
r'H://TCVFLDAT'), the code works right.
How else could I find the path in part-1 and use it in part 2?

POSIX/Linux uses a forward slash instead of a backslash (py: os.sep), and the delimiter in PATH is a colon instead of a semicolon (py: os.pathsep). There's no convention I know of to use trailing slashes.

Re: [Tutor] path directory backslash ending
Well, under the principle of least harm, it appears that since the trailing backslash causes no harm if omitted, but sometimes does if allowed, I removed them all. But that's in win 7. Is it okay to always omit them in Linux? Python33 is itself installed with a trailing backslash, so I figured this was a Linux habit. An entirely different question as long as I'm here. I have a local wamp server with mysql and phpadmin for php so I can test web pages locally. What's the equivalent for Python?

The trailing backslash shouldn't directly matter in the PATH variable, not as far how the system splits the string on ';' and searches the directories. It may be an issue with escaping if "%PATH%" is passed as a quoted argument. We can test this to be sure. Create test.py: import sys print(sys.argv[1:]) Now try an example. First without quotes: C:\>test.py C:\Program Files;C:\Python33\ ['C:\\Program', 'Files;C:\\Python33\\'] Obviously the C runtime (not the shell, as would be the case on a POSIX system) needs a little help parsing the argument string. We'll add some quotes around it: C:\>test.py "C:\Program Files;C:\Python33\" ['C:\\Program Files;C:\\Python33"'] Ack! The trailing backslash was treated as an escape character, so we end up with a trailing double quote. It works fine if you remove the trailing backslash: C:\>test.py "C:\Program Files;C:\Python33" ['C:\\Program Files;C:\\Python33'] OK, so IMHO don't use a trailing backslash. It's also a convention to not use a trailing backslash in directories set as environment variables. For example: C:\>echo %ProgramFiles% C:\Program Files This makes it look more natural as part of another path: C:\>dir /b "%ProgramFiles%\Microsoft SDKs\Windows\v7.0A" bin Include Lib Note that the shell replaces %ProgramFiles% literally with C:\Program Files, so quotes are required. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

There may be a Windows convention, but I doubt it. As far as I could tell when I was stuck in Windows, the only time a trailing backslash was significant was when there was nothing in front of it but a colon and/or a drive letter. In Linux, applications are free to make their own use of the trailing backslash, and I know that rsync does something different with it present than without.

Minor question. I was adding the Py Script directory to the Win 7 Path, and noticed that Python33 ends with a backslash but many directories do not. Is there a difference?

Oh cock, I missed a $ sign it should be "python $script". Seems to complain
about the path as well though, not sure about that one, I'll get back to you

Let me know if you didn't get it or it doesn't work. HTH, Adam. I got it, got sidetracked and then forgot to look at it again. Thanks for reminding me. Your idea works, but with one little downside. The directories I am working with are chapters in a book. So as I move from chapter to chapter I will need to change the bash script, but this seems to be less typing than using the terminal.

Nautilus. I have it configured to run files with the extension .py when
they are double clicked.
What do you mean, "use a launcher"? Use a launcher to do what? What sort
of launcher?
It runs programs and sits on the panel at the top of my Ubuntu desktop.
The command it uses is usr/bin/python2.6. These are wxPython examples I am
working with.
What pops up an error dialog? The launcher?
I am assuming Python. The title bar of the dialog says Python2 Error, the
message is Can't load image from file 'wxPython.jpg': file does not exist.
Which file does it claim doesn't exist? Python? The Python script? The
image file? What is the exact error message it gives?
See above. The line that triggers the error is: image =
wx.Image('wxPython.jpg', wx.BITMAP_TYPE_JPEG)
There's probably a way to tell the launcher which working directory to
use, but of course that depends on the answers to the above questions.
If I use the terminal to start the program it has no problem using the
file. There are multiple files in multiple directories so I was looking for
a way to just double click them and have them run. If it turns out that I
must make changes to or for each of the files it will be easier to just keep
using the terminal. I've only been using Ubuntu for a few months so I was
surprised that the program could not see a file that is in the same
directory.

The problem is ubuntu doesn't run the script from the directory it's in so
it's looking for wxPython.jpg somewhere else.
OK, I mistakenly thought that double-clicking on file in Nautilus would
take care of the path info.
In my reply above I also mentioned that I tried by dropping it on a
Launcher on the top panel and that the command the launcher uses is
usr/bin/python2.6. Is there a way that the command can be changed so
that it will look in the same directory the python script is in for any
file it needs?

If I use the terminal to start the program it has no problem using the
file. There are multiple files in multiple directories so I was looking
for a way to just double click them and have them run. If it turns out
that I must make changes to or for each of the files it will be easier
to just keep using the terminal. I've only been using Ubuntu for a few
months so I was surprised that the program could not see a file that is
in the same directory.

[Tutor] path to executing .py file
Hello everybody! I'm working on my code repository (svn) auto-backup script which get hotcopy of svn repository directory to a directory named by date in same location where script file is, it executed by a timer program every 00:00 clock. Everything works fine when I'm testing by double click it. But when auto execute it, I got unexpected behavior. The backup directory will be created under "C:\Documents and settings\username". I create backup directory by this way: os.mkdir(os.getcwd() + arch_dir) is there some way to get path to my executing script, so I can replaced "os.getcwd()" in above line? And I have another question, I've tried remove a copy of svn repository by calling shutil.rmtree(svn_repos_copy_dir) I got error "Access denied!" Is that mean my script has no power to delete it? Is there some way to give the right to do that? thanks tiefeng wu 2009-04-14 ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
