csv - Compare column name, then compare row data in Python -


so trying have csv file looks this:

"test_name", "mean", "median", "std_dev" "data name 1", 50, 75, 10 "data name 2", 52, 80, 11 "data name 1", 53, 79, 9  "data name 2", 55, 78, 8 "data name 3", 54, 77, 7 "data name 3", 53, 71, 7 "data name 1", 51, 72, 8

so right now, have program finds if test name equal each other. because if have same data name, want compare data have. 

import csv  csvfile = 'some.csv'  data = {}  open('some.csv') f:     reader = csv.dictreader(f)     row in reader:         (k,v) in row.items():                 try:                         data[k].append(v)                 except keyerror:                         data[k] = [v]  testnames = data['test_name'] mean = data['mean'] median = data['median'] std = data['stdev']  val in testnames:         val2 in testnames:                 if val == val2:                     index = testnames.index(val)                     index2 = testnames.index(val2)                      mediantemp = median[index]                     mediantemp2 = median[index2]                      if mediantemp2 > mediantemp:                             sub = mediantemp2 - mediantemp                             if sub > 100:                                     print "uh oh! @ ", val, "and ", val2 names

maybe, i'm doing little far off here. looking compare medians of data has same test name. struggling being able row data comparison after have compared test_names. have part working.

******* edit ********* trying use index() find element location now.

now issue having index , index2 exact same value. rather data name 1 giving index 0 , next data name 1 giving index2 of 2. both give 0.

any suggestions appreciated.

thanks :)

you can loop on index of testnames instead use indices access row data

for in range(len(testnames)):     j in range(len(testnames)):         if != j , testnames[i] == testnames[j]:             # access row data using: data['median'][i] data['median'][j]

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() .
