Python Enum: Get the unique enumeration values

Python Enum: Exercise-5 with Solution

Write a Python program to get the unique enumeration values.

Sample Solution:

Python Code:

import enum
class Countries(enum.Enum):
    Afghanistan = 93
    Albania = 355
    Algeria = 213
    Andorra = 376
    Angola = 244
    India = 355
    USA = 213
for result in Countries:
    print('{:15} = {}'.format(result.name, result.value))

Sample Output:

Afghanistan     = 93                                                                                          
Albania         = 355                                                                                         
Algeria         = 213                                                                                         
Andorra         = 376                                                                                         
Angola          = 244

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")
