Python Datetime: Exercise-57 with Solution

Write a Python program to get different time values with components timezone, timezone abbreviations, the offset of the local (non-DST) timezone, DST timezone and time of different timezones.

Sample Solution:

Python Code:

import time
import os
def zone_info():
   print('TZ   :', os.environ.get('TZ', '(not set)'))
   print('Timezone abbreviations:', time.tzname)
   print('Timezone : {} ({})'.format(
       time.timezone, (time.timezone / 3600)))
   print('DST timezone ', time.daylight)
   print('Time :', time.strftime('%X %x %Z'),'\n')
print('Default Zone:')
zone_info()
TIME_ZONES = [
   'Pacific/Auckland',
   'Europe/Berlin',
   'America/Detroit',
   'Singapore',
]
for zone in TIME_ZONES:
   os.environ['TZ'] = zone
   time.tzset()
   print(zone, ':')
   zone_info()

Sample Output:

Default Zone:
TZ   : (not set)
Timezone abbreviations: ('UTC', 'UTC')
Timezone : 0 (0.0)
DST timezone  0
Time : 11:30:05 04/13/21 UTC 

Pacific/Auckland :
TZ   : Pacific/Auckland
Timezone abbreviations: ('NZST', 'NZDT')
Timezone : -43200 (-12.0)
DST timezone  1
Time : 23:30:05 04/13/21 NZST 

Europe/Berlin :
TZ   : Europe/Berlin
Timezone abbreviations: ('CET', 'CEST')
Timezone : -3600 (-1.0)
DST timezone  1
Time : 13:30:05 04/13/21 CEST 

America/Detroit :
TZ   : America/Detroit
Timezone abbreviations: ('EST', 'EDT')
Timezone : 18000 (5.0)
DST timezone  1
Time : 07:30:05 04/13/21 EDT 

Singapore :
TZ   : Singapore
Timezone abbreviations: ('+08', '+08')
Timezone : -28800 (-8.0)
DST timezone  0
Time : 19:30:05 04/13/21 +08

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

The os and os.path modules.

The __file__ constant

os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")

os.path.dirname(path) (returns "the directory name of pathname path")

os.getcwd() (returns "a string representing the current working directory")

os.chdir(path) ("change the current working directory to path")
