pandas - Could I use python to retrieve a number of zip code within a radius -


picture: retrieve number of zip code within radius in excel

as can see on picture above, use excel expand target zip code (a list of zip code randomly type in). , can list of expanded zip code within 35 miles radius (it can 10 mils, 50 miles, depending on want at) of target zip code.

however, process takes long time, if have different groups of target zip code expand. thinking whether there more efficient way in python instead.

i know geopy can me distance between 2 zip code, cannot give list of zip within location.

for usa zip codes, there pyzipcode package.

single zip code query:

from pyzipcode import zipcodedatabase zcdb = zipcodedatabase() in_radius = [z.zip z in zcdb.get_zipcodes_around_radius('55001', 8)] # ('zip', radius in miles) radius_utf = [x.encode('utf-8') x in in_radius] # unicode list utf list

output:

>>> in_radius [u'54016', u'54021', u'55001', u'55003', u'55042', u'55043', u'55082', u'55129'] >>> radius_utf ['54016', '54021', '55001', '55003', '55042', '55043', '55082', '55129']

multiple zip codes @ once:

from pyzipcode import zipcodedatabase zcdb = zipcodedatabase() input_zips = [] input_zips = raw_input("enter zip codes (separated comma): ").replace(" ", "").split(",") # remove whitespace , split comma list input_radius = raw_input("enter radius entered zip code (in miles): ") # in python 3.x change both raw_input() input() y in range(0, len(input_zips)): # loop find , print radius lists     in_radius = [z.zip z in zcdb.get_zipcodes_around_radius(input_zips[y], input_radius)] # ('zip', radius in miles)     radius_utf = map(int, [x.encode('utf-8') x in in_radius]) # unicode list utf list , map convert str list int list     print("target zip: %s, radius %s miles, list of zip codes in radius:\n%s\n" %(input_zips[y], input_radius, radius_utf))

output:

enter zip codes (separated comma): 54021, 55001 enter radius entered zip code (in miles): 10 target zip: 54021, radius 10 miles, list of zip codes in radius: [54021, 55001, 55033, 55043, 55089, 55129]  target zip: 55001, radius 10 miles, list of zip codes in radius: [54016, 54021, 54082, 55001, 55003, 55016, 55033, 55042, 55043, 55082, 55090, 55115, 55125, 55129]

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
