Memory error Python Staircase -


hi i'm writing code grok learning(website) test i've been testing code on mac(messed schools should using pc) , nothing seems appear 1 min web page reloads , appears in area code displays it's running form:

traceback (most recent call last):   file "program.py", line 6, in <module>     print(" " * number + "|") memoryerror

can understanding i've never seen before? (code below)

a=0 number = int(input("how many steps? ")) print("__") if number != 1:   while < number:     print(" " * number + "|")     = + 1     print(" " * number + "_")     number = number * 2 elif number == 1:   print("__|")

the code making staircase using underscores , pipe characters user's input(screen shot of explanation included)

so assuming desired output input of 4: 

how many steps? 4 __   |__      |__         |__ ___________|

you can this: 

number = int(input("how many steps? ")) print("__") in range(1, number):     offset = a*2 + - 1     print(" " * (offset) + '|' + ('__' if < number else '')) offset = number*2 + number - 1 print("_" * (offset) + '|')

basically can rid of number != 1 check @ beginning since should behave identically input. loop on number of steps. @ each step offset, twice step number (a), plus offset previous pipe chars. check if there step after one, can put underscores on same line. finally, on last step (which outside loop), put underscore instead of whitespace , final pipe char

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() .
