Python: Find the specified number of maximum values in a given dictionary

Python dictionary: Exercise-59 with Solution

Write a Python program to find the specified number of maximum values in a given dictionary.

Sample Solution:

Python Code:

def test(dictt, N):
    result = sorted(dictt, key=dictt.get, reverse=True)[:N]
    return result 
dictt = {'a':5, 'b':14, 'c': 32, 'd':35, 'e':24, 'f': 100, 'g':57, 'h':8, 'i': 100}
print("\nOriginal Dictionary:")
print(dictt)
N = 1
print("\n",N,"maximum value(s) in the said dictionary:")
print(test(dictt, N))
N = 2
print("\n",N,"maximum value(s) in the said dictionary:")
print(test(dictt, N))
N = 5
print("\n",N,"maximum value(s) in the said dictionary:")
print(test(dictt, N))

Sample Output:

Original Dictionary:
{'a': 5, 'b': 14, 'c': 32, 'd': 35, 'e': 24, 'f': 100, 'g': 57, 'h': 8, 'i': 100}

 1 maximum value(s) in the said dictionary:
['f']

 2 maximum value(s) in the said dictionary:
['f', 'i']

 5 maximum value(s) in the said dictionary:
['f', 'i', 'g', 'd', 'c']

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")
