Python ascii.read tab(?) delimiters -


i trying use ascii.read scan in large number of tabulated data files. column headings not appear have self-consistent delimiters. there range 2 7 spaces between each column header. files looks this:

  k    waveln    neff       geom alb   bond/qfit  bond/geom  q-fitted    1  0.3000000    0.0556723    0.0000000    0.0000000    2.1435934    2.0582306 [...] [...]

i first suspected treat them tabs, not appear case:

raw = (ascii.read('filename', delimiter='\t')

will read file returns quite useless single column of data.

now, not problem under normal cases - simple

delimter='\s'

could have done trick. frustration, 1 column named "geom alb" - complete space in middle. fouls delimiter, thinks 2 column headers, not one:

raw = (ascii.read('filename',delimiter='\s') inconsistenttableerror: number of header columns (8) inconsistent data columns (7) @ data line 0

this solveable replacing "geom alb" header "geom_alb" in files in question, prefer avoid spending time write script this, particularly if there more simple , elegant solution.

i found workaround problem here. calling ascii.read as

raw = (ascii.read('filename',guess=false,header_start=none,data_start=2,names=('k','waveln','neff','geom alb','bond/qfit','bond/geom','q-fitted')))

i able bypass ascii.read's attempts find , apply header names , define them myself. key of course being

header_start=none

which tells ascii.read there no headers.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
