basically have no idea how this. but if have multiple array: [[1, 2], [3, 4] which can seen as: ([[x, y], [x, y]...]) and want create new array x , separated 4 sectors: (1, 2, 3, 4) array_(number(y)) = [x, 0, 0, 0] if f.e x = 1 , y = 2 should this: array_2 = [0, x, 0, 0] i'm sorry not posting code begin with, literally have 0 ideas. can me come something? you can achive using itertools: import itertools xyarray = [[1,2],[3,4]] xarray = list(itertools.chain(*xyarray))

i have series of sql select statements need run python script using mysqldb. 1 of variables pass select statements called unit_ids . i've tried treating unit_ids string tuple of strings. initially, backslashes being inserted string. after looking around online, i've been able avoid backslashes, quotation marks being inserted instead. here current code: connection = mysqldb.connect('localhost', 'root', '*****', 'test') cur = connection.cursor unit_ids = ('0a1', '0a2', '0a3', '0a4') attr = 'sample' cur.execute("""select count(*) test attribute = %s , unit_id in %r""", (a, tuple(unit_ids))) using cur._last_executed , can see actual sql statement performed was: select count(*) test attribute = 'sample' , unit_id in ("'0a1'", "'0a2'", "'0a3'", "'0a4'") any ideas on need change in order hav...

i working sas code. data a; i=1 10000000; x = 12 + 2.5*rannor(0); y = 15000 + 2500*x + 5000*rannor(0); output; end; i having hard time in attempt find suitable r code can replicate (or rather similar) i've done above. all i've been able this... set.seed(0) x = 12 +2.5*rnorm(1) y = 1500+ 250*x+ 500*rnorm(1) ...but think sas program generates 10000000 x's , y's have values based on equations above, assume dataframe involved. anyone used r or/and sas before? ideas how can similar sas code? set.seed(0) n = 10000000 library(dplyr) data_frame(x = 12 + 2.5*rnorm(n), y = 1500+ 250*x+ 500*rnorm(n) )
