[Numpy-discussion] loadtxt stop

oops, I meant to save my post but I sent it instead - doh!
In the end, the question was; is worth adding start= and stop= markers into
loadtxt to allow grabbing sections of a file between two known headers? I
imagine it's something that people come up against regularly.

Subject: loadtxt stop
I been looking around and could spot anything on this. Quite often I want to
read a homogeneous block of data from within a file. The skiprows option is
great for missing out the section before the data starts, but if there is
anything below then loadtxt will choke. I wondered if there was a possibility
to put an endmarker= ?
For example, if I want to load text from a large! file that looks like this
1 2.0 3.0
2 4.5 5.7
500 4.3 5.4
1 2.0 3.0 3.14 1.1414
2 4.5 5.7 1.14 3.1459
500 4.3 5.4 0.000 0.001
Then I can use skiprows=2, but loadtxt will choke when it gets to 'END'. To
