Thanks to discover this bad documentation page.

instead of elev.rows it is possible to use len(elev) to get the number
of rows, and insetad usig a variable to get the row number use just:

{{{
for irow, row in enumerate(elev):
new[irow] = row < 144
}}}

please replace the example with enumerate.

All the best

[GRASS-dev] error in pygrass doc

2016-01-08 Thread Luca Delucchi 
Hi devs,

A friend found the following problem in the raster pygrass documentation [0]

>>> elev=RasterSegment('elevation_raster')
>>> elev.open()
>>> for row in elev[:5]: print(row[:3])
...

I suggest him to use

x = 0
for irow in elev:
new[x] = irow<144
x += 1


maybe there is a better solution, otherwise I can replace the wrong
code in the doc with this solution.
