Re: Delete first line from file

[Pieter Claerhout]

what about the following?

f = open( 'file.txt', 'r' )
lines = f.readlines()
f.close()

f = open( 'file.txt'.'w' )
f.write( '\n'.join( lines[1:] ) )
f.close()

cheers,


pieter

RE: Finding a script's home directory?

[Pieter Claerhout]

The following should work:

os.path.split( os.path.realpath( sys.argv[0] ) )[0]

Subject: Finding a script's home directory?

In one of my python programs has a data file I need to load. My solution 
was to say:

if os.path.exists(os.path.join(os.getcwd(), "config.xml")):
self.cfgfile = os.path.join(os.getcwd(), "config.xml")

Which works fine... as long as you're *in* the script's home directory 
when you run it (as in, run it as: ./startApp.py as opposed to 
./myApp/startApp.py).

If I run it from an alternate directory the program looks for the 
config.xml file in my current directory not the app's home directory. So 
how do I get the script's home directory?
