python - convert file path list to tree -


there python file path list below:

file_path_list = ["test/dir1/log.txt", "test/dir1/dir2/server.txt", "test/manage/img.txt"]

i want convert tree. expect result below:

 tree_data = [     {       "path": "test",       "children": [         {           "path": "dir1",           "children": [             {               "path": "log.txt"             },             {               "path": "dir2",               "children": [                 {                   "path": "server.txt"                 }               ]             }           ]         },         {           "path": "manage",           "children": [             {               "path": "img.txt",             }           ]         }       ]     }   ]

what's best way convert?

update: code below, think it's not well. 

    def list2tree(file_path):         """convert list tree."""         tree_data = [{             "path": "root",             "children": []         }]         f in file_path:             node_path = tree_data[0]             pathes = f.split("/")             i, p in enumerate(pathes):                 length = len(node_path["children"])                 if not length or node_path["children"][length - 1]["path"] != p:                     # create new node                     new_node = {                         "path": p,                     }                     if != len(pathes) - 1:  # middle path                         new_node["children"] = list()                     node_path["children"].append(new_node)                     node_path = new_node                 else:                     node_path = node_path["children"][length - 1]         return tree_data

i think way not best. ideas? thank much!

one way split strings @ '/' , put them in defaultdict of defaultdicts, see defaultdict of defaultdict, nested.

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() .
