Thanks Chris! Thanks for the quick reply. Indeed this is the case! I have
now written out a new list, instead of modifying the list I am iterating
over.

st is: ['44', '', '', '0.0\n']
The code above removes all the empty strings in the middle, all except
two. My code seems to miss two of the empty strings.
Would you know why this is occuring?
Regards,
Helvin

Error msg says: UnboundLocalError: local variable 'no_picked'

For some reason, no_picked does not increment, but the printing
statement works.
Do you know why?
(I'm actually writing this for a vtkrenderwindowinteractor.)

27;I found geometry' is printed. However,
if instead of using file_str.find(), I use file_str.endswith(), it
does not exhibit this strange behaviour.
Obviously, I want the elif line to be true, instead of the first if
statement.
Does anyone know why this is happening?
Help much appreciated!
Very puzzled,

Just wanted to say, to convert qstrings (or integers for that matter)
to strings, use the str() function.

My VTK stuff are now displayed in my GUI! =D
Welcome to ask, if my blog is not detailed enough. I just wasn't
bothered to put my entire file on there.

Hi everyone,
I am writing some python script that should find a line which contains
'1' in the data.txt file, then be able to move a certain number of
lines down, before replacing a line. At the moment, I am able to find
the line '1', but when I use f.seek to move, and then rewrite, what I
write g

but I don't know how to use it in my
code, as when I run it, an error says it can't find the vtk module.
Help would be so appreciated!
