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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
