在分支日期時間前添加城市名稱

Question

我有三個分支位置與城市相關的時間，但是我不知道如何在時間前寫下城市名稱。有人請幫助我嗎？

感謝

from datetime import datetime 
from pytz import timezone 
import pytz 

portland_time = datetime.now(tz=pytz.UTC).replace(microsecond=0) 
Portland = portland_time.astimezone(pytz.timezone('US/Pacific')) 

new_york_time = portland_time.astimezone(timezone('US/Eastern')) 
Ny = new_york_time 

london_time = portland_time.astimezone(timezone('Europe/London')) 
London = london_time 

cities = {'Portland': Portland, 
      'Ny': Ny, 
      'London': London} 

def branches(): 
    for city in cities: 
     Branchtime=int(cities[city].strftime('%H')) 
     if Branchtime >= 9 and Branchtime < 21: 
      print(city, cities[city], 'OPEN') 
     else: 
      print(city, cities[city], 'CLOSED') 
branches()

你介意使用的dict代替list您cities？如果沒有，你可以這樣做：

from datetime import datetime 
from pytz import timezone 
import pytz 

portland_time = datetime.now(tz=pytz.UTC).replace(microsecond=0) 
Portland = portland_time.astimezone(pytz.timezone('US/Pacific')) 

new_york_time = portland_time.astimezone(timezone('US/Eastern')) 
Ny = new_york_time 

london_time = portland_time.astimezone(timezone('Europe/London')) 
London = london_time 

cities = {'Portland': Portland, 
      'Ny': Ny, 
      'London': London} 

for city in cities: 
    Branchtime=int(cities[city].strftime('%H')) 
    if Branchtime >= 9 and Branchtime < 21: 
     print(city, cities[city], 'OPEN') 
    else: 
     print(city, cities[city], 'CLOSED')
