Python Arrow Module: Create a datetime from a given timezone-aware datetime using arrow module

Arrow Module: Exercise-3 with Solution

Write a Python program to create a datetime from a given timezone-aware datetime using arrow module.

Sample Solution:

Python Code:

import arrow
from datetime import datetime
from dateutil import tz
print("\nCreate a date from a given date and a given time zone:")
d1 = arrow.get(datetime(2018, 7, 5), 'US/Pacific')
print(d1)
print("\nCreate a date from a given date and a time zone object from a string representation:")
d2 = arrow.get(datetime(2017, 7, 5), tz.gettz('America/Chicago'))
print(d2)
d3 = arrow.get(datetime.now(tz.gettz('US/Pacific')))
print("\nCreate a date using current datetime and a specified time zone:")
print(d3)

Sample Output:

Create a date from a given date and a given time zone:
2018-07-05T00:00:00-07:00

Create a date from a given date and a time zone object from a string representation:
2017-07-05T00:00:00-05:00

Create a date using current datetime and a specified time zone:
2019-06-01T00:55:57.935800-07:00

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")
