Examples
Iterating through array item-by-item
from scidb4py import Connection
conn = Connection('localhost', 1239)
conn.open()
array = conn.execute("select * from array(<a:int32>[x=0:3,2,0], '[0,1,2,3]')")
for pos, val in array:
print '%d - %d' % (pos['x'], val['a'])
conn.close()
Iterating through array chunk-by-chunk, item-by-item
from scidb4py import Connection
conn = Connection('localhost', 1239)
conn.open()
array = conn.execute("select * from array(<a:int32 null>[x=0:2,3,0, y=0:2,3,0], '[[1,2,3][4,5,6][7,8,9]]')")
while not array.end:
while not array.chunk_end:
print '%s - %s' % (array.get_coordinates(), array.get_item("a"))
array.next_item()
array.next_chunk()
conn.close()
