python - How to read Txt file section by section by special marker using Pandas? -


i trying use pandas analyze text file output s structural analysis software. file has 24000+ lines can broken down sections, each of them starting $, example:

$ stories - in sequence top   story "platform"  height 51.9996    story "bulkhead"  height 117    story "emr"  height 124.9992    story "roof"  height 140.0004 similarto "41st fl"    $ grids   gridsystem "g1"  type "cartesian"  bubblesize 60    grid "g1"  label "g"  dir "x"  coord -1068 visible "yes"  bubbleloc "end"     grid "g1"  label "d"  dir "x"  coord -586 visible "yes"  bubbleloc "end"     grid "g1"  label "d.3"  dir "x"  coord -460 visible "yes"  bubbleloc "end"

i can use pd.read_csv , specify skip_row parameter each of them, pretty repetitive , stupid when text file large. since output file quite formatted, there way parse text file sections headline of $..., , create pd.dataframe lines below $...?

i guess useful have specify number of txts:

marker = '$' txt1, txt2, txt3, txt4 = txt.split(marker)

also, able specify regex rule marker?

you can make sections split function (and don't have specify number of txts). split function returns list object. each element of list represent section.

sections = txt.split("$")

now can iterate through list.

for actual_section in sections:     print actual_section

for more information read documentation split function here.

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...

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() .
