Python Enum: Exercise-1 with Solution

Write a Python program to create an Enum object and display a member name and value.

Sample Solution:

Python Code:

from enum import Enum
class Country(Enum):
    Afghanistan = 93
    Albania = 355
    Algeria = 213
    Andorra = 376
    Angola = 244
    Antarctica = 672
print('\nMember name: {}'.format(Country.Albania.name))
print('Member value: {}'.format(Country.Albania.value))

Sample Output:

Member name: Albania                                                                                          
Member value: 355

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")
