Get a list of time zones using Python
When developing real-world applications, software developers must ensure that the application can support users from both their own country and other parts of the world. Since most countries have different time zones and many people around the world constantly cross countries for work and travel purposes, absolute date and time values cannot be stored in a database.
协调世界时To solve this problem, we store UTC or TIMEZONE values
in the database 标准时间. They are converted on the fly to the actual time zone based on the user's current location.
Now, there are so many time zones that rewriting them every time we start a new development project would be akin to reinventing the wheel. Therefore, developers create libraries that contain all these time zones and utilities for working with dates, times, and time zones.
This article will show you how to get a list of time zones using Python.
Get a list of time zones using Python
Python has a module pytzthat contains the Olson tzdatabase or time zone database. This library allows developers to accurately perform cross-time zone calculations such as conversions and daylight saving time. We can use this library to retrieve all available time zones.
Use the following pipcommand to install this library.
pip install pytz
Now, let us understand how to use this library to get all available time zones through the following Python code.
import pytz
timezones = pytz.all_timezones
print(timezones)
Output:
['Africa/Abidjan', 'Africa/Accra', 'Africa/Addis_Ababa', 'Africa/Algiers', 'Africa/Asmara', 'Africa/Asmera', 'Africa/Bamako', 'Africa/Bangui', 'Africa/Banjul', 'Africa/Bissau', ..., 'US/Central', 'US/East-Indiana', 'US/Eastern', 'US/Hawaii', 'US/Indiana-Starke', 'US/Michigan', 'US/Mountain', 'US/Pacific', 'US/Samoa', 'UTC', 'Universal', 'W-SU', 'WET', 'Zulu']
pytzThe library has a variable all_timezoneswhich is a list, which contains all available time zones. This module also has a variable all_timezones_set, an array of all available time zones.
The output of the above Python code is one ..., because the number of time zones is so large, the output has been trimmed for better understanding. If you want to see all available time zones, execute the above Python code.
