Python: Check all values are same in a dictionary

Python dictionary: Exercise-45 with Solution

Write a Python program to check all values are same in a dictionary.

Sample Solution:

Python Code:

def value_check(students, n):
    result = all(x == n for x in students.values()) 
    return result
  
students = {'Cierra Vega': 12, 'Alden Cantrell': 12, 'Kierra Gentry': 12, 'Pierre Cox': 12}
print("Original Dictionary:")
print(students)
n = 12
print("\nCheck all are ",n,"in the dictionary.")
print(value_check(students, n))
n = 10
print("\nCheck all are ",n,"in the dictionary.")
print(value_check(students, n))

Sample Output:

Original Dictionary:
{'Cierra Vega': 12, 'Alden Cantrell': 12, 'Kierra Gentry': 12, 'Pierre Cox': 12}

Check all are  12 in the dictionary.
True

Check all are  10 in the dictionary.
False

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")
