pandas - Translating Zip, OrderedDict and DataFrame from Python to Typescript -


i have following code in python:

import pandas pd import numpy np import collections import copy  weekdays = { 1 : 'null', 2 : 'null', 3 : 'null', 4 : 'null', 5 : 'null', 6 : 'null', 7 : 'null'} months = ['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec']  days_in_month_in_year = {'2017' : [31, 28, 31, 30, 31, 30, 31, 31, 30, 30, 30, 31], '2018' : [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31], '2019' : [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31],'2020' : [31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] } days_in_month_in_year = pd.dataframe(days_in_month_in_year, index=months)   startday = 7 month = 0 dict_of_months = collections.ordereddict()  index, row in days_in_month_in_year.iterrows():     month_name = months[month]     print (month_name)     days_in_month = (row['2019'])       month_df = pd.dataframe({}, columns=[1, 2, 3, 4, 5, 6, 7])      error_flag = 0     i, key in enumerate(weekdays, 1):         if startday < 1 or startday > 7:             error_flag = 1             break         elif < startday:             weekdays[key] = "null"             month_df.set_value(0, i, "null")         else:             j = (i - startday) + 1             weekdays[key] = j             month_df.set_value(0, i, j)      key, j in zip(weekdays.keys(), range(j, days_in_month)):         month_df.set_value(1, key, j + 1)      key, j in zip(weekdays.keys(), range(j + 1, days_in_month)):         month_df.set_value(2, key, j + 1)      key, j in zip(weekdays.keys(), range(j + 1, days_in_month)):         month_df.set_value(3, key, j + 1)      key, j in zip(weekdays.keys(), range(j + 1, days_in_month)):         month_df.set_value(4, key, j + 1)      key, j in zip(weekdays.keys(), range(j + 1, days_in_month)):         month_df.set_value(5, key, j + 1)      month_df = month_df.fillna("null")      if len(month_df.index) < 6:         null_row = pd.series(['null', 'null', 'null', 'null', 'null', 'null', 'null'], [1,2,3,4,5,6,7])         month_df = month_df.append([null_row], ignore_index=true)      startday = startday + ( days_in_month % 7 )     if startday > 7:         startday = startday - 7      print (month_df)     print (startday)     month = month + 1      dict_of_months[month_name] = month_df  print (dict_of_months)

i need translate typescript. don't want people me in entirety, thought best include whole python code completeness.

so best ways reproduce behaviour of ordereddict in typescript??

how if want reproduce behaviour of zip?

what dataframes? structure should use?

here ts far. thin coz stumped start - heroes creates array of html objects in html file, , array output to:

import { component, oninit } '@angular/core';  @component({   selector: 'app-events',   templateurl: './events.component.html',   styleurls: ['./events.component.css'] }) export class eventscomponent implements oninit {  weekdays: []; monthslist: []; startday: number; month: number; heroes: [];       ngoninit() {     this.heroes = [   { name: '' },   { name: '' },   { name: '' },   { name: '' },   { name: '' },   { name: '' },   { name: '' },   { name: '' },   { name: '' } ];     this.weekdays = ['null', 'null', 'null', 'null', 'null', 'null', 'null'];     this.monthslist = ['jan', 'feb', 'mar', 'apr', 'may', 'jun', 'jul', 'aug', 'sep', 'oct', 'nov', 'dec'];     this.startday = 7;     this.month = 0;   }  }

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)

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
