Renaming of files in OS directory
Hi, all, I am writing a program that renames files inside OS
directories the user provides. I am at the early stage of writing it
and I encountered some problems.
Below is my code. There is an error i received when i run this code.
The error is, WindowsError: [Error 123] The filename, directory name,
or volume label syntax is incorrect.
Hope you guys could help.
import os, glob
def fileDirectory():
#Asks the user for a file root directory
fileroot = raw_input("Please input the file root directory \n\n")
print fileroot
#Returns a list with all the files inside the file root directory
os.listdir(fileroot)
fileDirectory()

I do not get what you mean. The string i passed in is stored inside the variable fileroot. In the case I tested, i inputed the string "C: \" inside the raw_input and stored it inside fileroot, I tried printing repr(fileroot) and it gave me "C:\" as the result and when i tried running os.listdir(fileroot) i got the error.

Sorry, This is my first time using the os commands in python, Ok,
firstly, I entered "C:\" inside raw_input and stored it inside
fileroot. When i print repr(fileroot), my result was '"C:\\"' . And
when I run os.listdir with fileroot, I got that error. I typed my
os.listdir code like this: os.listdir(fileroot)
I attached my code for reference, thanks again!
import os, glob
def fileDirectory():
# Ask user for file directory input
fileroot = raw_input("Input")
print repr(fileroot)
#Returns a list with all the files inside the file root
directory( The error occurs here )
os.listdir(fileroot)
fileDirectory()

simple renaming files program
Hi, all, I am working on a simple program that renames files based on
the directory the user gives, the names the user searched and the
names the user want to replace. However, I encounter some problems.
When I try running the script, when it gets to the os.rename part,
there will be an error. The error is :
n = os.rename(file, file.replace(s, r))
WindowsError: [Error 2] The system cannot find the file specified
I attached my code below, hope you guys can help me, Thanks!
import os
directory = raw_input("input file directory")
s = raw_input("search for name")
r = raw_input("replace name")
for file in os.listdir(directory):
n = os.rename(file, file.replace(s, r))
print n

Creating a custom UI inside Maya with python
Hi, all, I wonder if my post is relevant here, but i will still post
it anyway. I am working on creating a custom UI inside Maya and I
encountered some problems. Firstly, I am trying to create a textfield
button that creates a locator-shaped curve based on the coordinates
the user keyed into the text field. However I got no idea how to go
about doing it properly. I hope you guys could give me some help.
Thanks. I attached my code below. My code isn't working though. I have
this error, which says button2 is not defined. I got no clue on how
else to debug.
import maya.cmds as cmds
def createMyLayout():
window = cmds.window(widthHeight=(1000, 600), title="test",
resizeToFitChildren=1)
cmds.rowLayout("button1, button2, button3", numberOfColumns=5)
cmds.columnLayout(adjustableColumn=True, columnAlign="center",
rowSpacing=10)
button2 = cmds.textFieldButtonGrp(label="LocatorCurve",
text="Please key in your
coordinates",
changeCommand=edit_curve,
buttonLabel="Execute",
buttonCommand=locator_curve)
cmds.setParent(menu=True)
cmds.showWindow(window)
def locator_curve(*args):
# Coordinates of the locator-shaped curve.
crv = cmds.curve(degree=1,
point=[(1, 0, 0),
(-1, 0, 0),
(0, 0, 0),
(0, 1, 0),
(0, -1, 0),
(0, 0, 0),
(0, 0, 1),
(0, 0, -1),
(0, 0, 0)])
return crv
def edit_curve(*args):
parts = button2.split(",")
print parts
x = parts[0]
y = parts[1]
z = parts[2]

Renaming OS files by file type in python
Hi all, I am creating a program that renames all files of the similar
file type. But i am stuck at this part. I tried running this code and
I got this error:new_name = os.rename(path, newpath)
WindowsError: [Error 183] Cannot create a file when that file already
exists. Hope you guys could help.

How do I get number of files in a particular directory.
Hi, all, Is there a way to get a number of files in a particular directory? I tried using os.walk, os.listdir but they are return me with a list, tuple of the files, etc. But I want it to return a number. Is it possible? -- http://mail.python.org/mailman/listinfo/python-list
Re: How do I get number of files in a particular directory.
Hi, I tried that, but it doesn't seem to work. My file directory has
many different files extensions, and I want it to return me a number
based on the number of files with similar files extensions. But when I
tried running it, I get many weird numbers. Below is my code i had so
far and the result.
import os
directory = raw_input("Please input file directory. \n\n")
s = raw_input("Please input a name to replace. \n\n")
ext = raw_input("input file ext")
for files in os.listdir(directory):
if ext in files:
file_number = len(files)
print file_number
The result is:
13
13
13
6
15
8
10
10
8
7
5
where the result should be just 11. Can anyone help me? Thanks.

Hi, I want to make it such that the user inputs a file extension and
it prints the number of similar file extensions out.
I tried doing this:
directory = raw_input("input file directory")
ext = raw_input("input file ext")
file_list = len(glob.glob(ext))
print file_list
And my result was this:
0
which it is suppose to be 11
May I know why? And how do I specify which directory it is searching
the files extension from? I want the user to specify a directory and
it searches the particular directory for the particular file
extensions and prints the number out.
Hope you guys could help.
Thanks
