Timezone Examples

In the previous chapter, you saw one timezone: America/Edmonton. But the total number of even common timezones is quite big: more than 400! But you can see, that timezone by default contain continent name and city. So, we can explore the variety of timezones across the specific continent.

Since .all_timezones and common_timezones methods return lists, we can easily iterate over them. For example, using list comprehension, we can easily count the number of timezones containing 'America'.


              
123456

            
# Load library
import pytz

# Count number of american timezones using list comprehension
american_timezones = len([x for x in pytz.common_timezones if 'America' in x])
print(f"There are {american_timezones} american timezones available in pytz.common_timesones.")
copy

Task

Iterate over .common_timezones and print only timezones containing Europe.

Task

Iterate over .common_timezones and print only timezones containing Europe.
