I wrote a script to rename a txt file in pythonwin as below.
import os
os.rename("northrdge.txt","northrdgechg.txt")
the above text file is in the path:C:\Users\gmayil\Desktop\northrdge.txt.
after this when i run the script i met below error:
Can anyone please help me on this ?

os.rename("northrdge.txt","northrdgechg.txt")
WindowsError: [Error 2] The system cannot find the file specified
Your python-file lies in "C:\Python27\Tools\gopi\renamefile.py", but you say your txt-file is in "C:\Users\gmayil\Desktop\". If you pass a relative path, python searches in its own directory, which is "C:\Python27\Tools\gopi\".
So all you have to do is giving the complete path:
os.rename("C:\Users\gmayil\Desktop\northrdge.txt", "C:\Users\gmayil\Desktop\northrdgechg.txt")

I don't understand the syntax to call the render feature of ERAlchemy (https://pypi.org/project/ERAlchemy see "Usage for Python"). I am using Python 2.7, sqlite3, and PyCharm. I have ERAlchemy, GraphViz, and PyGraphViz installed.
I am trying the following, but it cannot connect to the database:
from eralchemy import render_er
render_er("sqlite:///C:\\Users\\myname\\Documents\\Work\\pythonsqlite.db", 'erd_from_sqlite.png')
And this is the error:

Ah! Found the answer here
had to find the folder with "dot.exe" and add it to the environment variables -> system variables -> path
how can I create a file in python if the filename contains '/'
url='https://www.udacity.com/cs101x/index.html'
f=open(url,'w')
f.write('123')
f.close()
above code produces an error as
Traceback (most recent call last):
File "9.py", line 2, in <module>
f=open(url,'w')
IOError: [Errno 22] invalid mode ('w') or filename:https://www.udacity.com/cs101x/index.html'
Use os.path.basename() to isolate the filename.
import os
url='https://www.udacity.com/cs101x/index.html'
filename = os.path.basename(url)
f=open(filename,'w')
f.write('123')
f.close()
This will create a file called index.html
I am trying to package a kivy application for Windows, and after following the instructions in the Kivy website for the example TouchTracer app, I get an ImportError: No Module named ConfigParser message when trying to open the .exe file in the dist folder.
I am running Python 2.7.11 and kivy 1.9.1.
Also, while executing the command python -m PyInstaller..., the output includes a line that says:

Below is the traceback printed when attempting to open the .exe file.

I had the same problem for my kivy application, and I found an ad hoc solution. The error comes from the line "import kivy", so uncomment it and the next line "kivy.require('1.0.6')". There lines are unnecessary if your kivy has proper version.
I want to loop through the files present in Audio_files folder and check if it is raw file or wave file and put it in the respective directories.
Here is my code:
import shutil
import os
source = os.listdir("/home/GM/codec_implement/Audio_files/")
destination = "/home/GM/codec_implement/raw_files/"
destination2 = "/home/GM/codec_implement/raw_files/wave_files/"
for files in source:
if files.endswith(".wav"):
shutil.copy(files,destination)
elif files.endswith(".raw"):
shutil.copy(files,destination)
else:
print "Invalid format"
Please let me know where I am making mistake. Error i get is:
Traceback (most recent call last): File "./checkaudiofiles.py", line
12, in shutil.copy(files,destination) File
"/usr/lib/python2.7/shutil.py", line 119, in copy copyfile(src, dst)
File "/usr/lib/python2.7/shutil.py", line 82, in copyfile with
open(src, 'rb') as fsrc: IOError: [Errno 2] No such file or directory:
'test_sound.wav'
The error means that the test_sound.wav file is not on that directory. These file might be removed between the two proces or the os.listdir() and the shutil.copy() don't list the files the same way.
