How Can Python's pytz Library Display Time in Different Time Zones?

Displaying Time in Alternate Time Zones with Python's pytz

Introduction:

Many applications require converting and displaying time across different time zones. Determining the current time in any given zone can be a challenge without the right tools.

Solution:

The Python pytz library offers a convenient way to manipulate time zones and display time in a different time zone. The following is an elegant solution:

from datetime import datetime
from pytz import timezone    

south_africa = timezone('Africa/Johannesburg')
sa_time = datetime.now(south_africa)
print(sa_time.strftime('%Y-%m-%d_%H-%M-%S'))

This code retrieves the current time in the South African time zone and prints it in the specified format.

Explanation:

1. from datetime import datetime: Imports the datetime class.
2. from pytz import timezone: Imports the timezone class.
3. south_africa = timezone('Africa/Johannesburg'): Creates a timezone object for South Africa (using the 'Africa/Johannesburg' identifier).
4. sa_time = datetime.now(south_africa): Retrieves the current time in the South African time zone.
5. print(sa_time.strftime('%Y-%m-%d_%H-%M-%S')): Formats and prints the South African time in the specified format.

This method provides a straightforward and extensible way to display time in any desired time zone.
