Python timezone challenge- Day 17

the challenge here is to let the user choose the time zone from list of time zones and accordingly display the time

  
import datetime
import pytz

available_zones ={"1":"African/Tunis",
 "2":"Asia/Kolkata",
 "3":"Australia/Adelaide",
 "4":"Europe/Brussels",
 "5":"Europe/London",
 "6":"Japan",
 "7":"Pacific/Tahiti"
}
print("Please Choose the timezone (or 0 to quit)")
for place in sorted(available_zones):
    print("\t {} : {}".format(place,available_zones[place]))

while True:
    choice = input()
    if choice == 0:
        break
    if choice in available_zones.keys():
        tz_to_display = pytz.timezone(available_zones[choice])
        world_time = datetime.datetime.now(tz=tz_to_display)
        print ("The time in {} is {} {} ".format(available_zones[choice],
                             world_time.strftime("%A %x %X %z"),world_time.tzname()))
        print("LocalTime is {}".format(datetime.datetime.now().strftime("%A %x %X %z")))
        print("UTCTime is {}".format(datetime.datetime.utcnow().strftime("%A %x %X %z")))

 

Python timezone - Day 16(1 day later)

pip command,if it doesn't work ,open the python setup goto modify and check the add python to environment variables option python time zone library package,pip3 install pytz

  
import pytz
import datetime
country = "Europe/Moscow" #check for the spelling and case sensitivity
tz_to_display = pytz.timezone(country)
# print(tz_to_display)
# print(country)
print("The time in {} is {}".format(country,datetime.datetime.now(tz=tz_to_display)))
print("UTC is {}".format(datetime.datetime.utcnow()))
print("LocalTime here is {}".format(datetime.datetime.now()))
tz_to_display = pytz.timezone("Singapore")
print("The time in {} is {}".format("Singapore",datetime.datetime.now(tz=tz_to_display)))

#list of all timezones
for x in pytz.all_timezones:
    print(x)
print("=="*50)
print(pytz.country_names)
#list of all countries
for x in pytz.country_names:
    print(x)

for x in sorted(pytz.country_names):
    print(x + ": " + pytz.country_names[x])

#although the below code will run,there will be error ,since the few countries
#like (Bouvet Island ) have not defined the timezones
# for x in sorted(pytz.country_names):
#     print("{} : {} : {}".format(x,pytz.country_names[x],pytz.country_timezones(x)))

print("=================="*10)
#we can use the get method to avoid the below issue
for x in sorted(pytz.country_names):
    print("{} : {} : {}".format(x,pytz.country_names[x],pytz.country_timezones.get(x)))
print("*************"*10)
#we can also use the below method
for x in sorted(pytz.country_names):
    print("{} : {} ".format(x,pytz.country_names[x],end = ' '))
    if x in (pytz.country_timezones):
        print(pytz.country_timezones[x])
    else:
        print("TimeZone Not Defined")
