python - Loop doesn't process other files in the directory - 


me=1  while (me < 244):     f=open('%s' % me, 'rb')      tdata = f.read()     f.close()      ss = '\xff\xd8'     se = '\xff\xd9'      count = 0     start = 0     while true:         x1 = tdata.find(ss,start)         if x1 < 0:             break         x2 = tdata.find(se,x1)         jpg = tdata[x1:x2+1]         count += 1         fname = 'extracted%d03.jpg' % (count)         fw = open(fname,'wb')         fw.write(jpg)         fw.close()         start = x2+2         me=me+1

i trying run multiple files. operation file 1 , rest of files ignored. new python can tweak bit?

in last line of code you're incrementing me inside of nested while loop want run each of files. fix it, un-indent me so.

#!/usr/bin/python  me=1  while (me < 244):     f=open('%s' % me, 'rb')      tdata = f.read()     f.close()      ss = '\xff\xd8'     se = '\xff\xd9'      count = 0     start = 0     while true:         x1 = tdata.find(ss,start)         if x1 < 0:             break         x2 = tdata.find(se,x1)         jpg = tdata[x1:x2+1]         count += 1         fname = 'extracted%d03.jpg' % (count)         fw = open(fname,'wb')         fw.write(jpg)         fw.close()         start = x2+2      me=me+1  # needs outside of nested while loop

that being said, want improve names of variables in code (make them more descriptive!), , idea extract code in while loop function. it's worth mentioning outer while loop can (and should be) replaced loop.

something this:

def do_something_with_file(me):     f=open('%s' % me, 'rb')      tdata = f.read()     f.close()      ss = '\xff\xd8'     se = '\xff\xd9'      count = 0     start = 0     while true:         x1 = tdata.find(ss,start)         if x1 < 0:             break         x2 = tdata.find(se,x1)         jpg = tdata[x1:x2+1]         count += 1         fname = 'extracted%d03.jpg' % (count)         fw = open(fname,'wb')         fw.write(jpg)         fw.close()         start = x2+2   in range(1, 244):     do_something_with_file(i)

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() .
