Python: Find shortest list of values with the keys of a dictionary

Python dictionary: Exercise-60 with Solution

Write a Python program to find shortest list of values with the keys in a given dictionary.

Sample Solution:

Python Code:

def test(dictt):
    min_value=1
    result = [k for k, v in dictt.items() if len(v) == (min_value)] 
    return result    

dictt = {
 'V': [10, 12],
 'VI': [10],
 'VII': [10, 20, 30, 40],
 'VIII': [20],
 'IX': [10,30,50,70],
 'X': [80]
 }

print("\nOriginal Dictionary:")
print(dictt)
print("\nShortest list of values with the keys of the said dictionary:")
print(test(dictt))

Sample Output:

Original Dictionary:
{'V': [10, 12], 'VI': [10], 'VII': [10, 20, 30, 40], 'VIII': [20], 'IX': [10, 30, 50, 70], 'X': [80]}

Shortest list of values with the keys of the said dictionary:
['VI', 'VIII', 'X']

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")
