45. Verify All Dictionary Values are the Same

Write a Python program to verify that all values in a dictionary are the same.

Visual Presentation:

Sample Solution:

Python Code:

# Define a function 'value_check' that checks if all values in a dictionary are equal to a given value 'n'.
def value_check(students, n):
    # Use the 'all' function to check if all values in the 'students' dictionary are equal to 'n'.
    result = all(x == n for x in students.values())
    return result

# Create a dictionary 'students' with student names as keys and values representing their scores.
students = {'Cierra Vega': 12, 'Alden Cantrell': 12, 'Kierra Gentry': 12, 'Pierre Cox': 12}

# Print a message indicating the start of the code section and the original dictionary.
print("Original Dictionary:")
print(students)

# Set the value 'n' to be checked to 12.
n = 12

# Print a message indicating the intention to check if all values in the dictionary are equal to 'n'.
print("\nCheck all are", n, "in the dictionary.")

# Call the 'value_check' function to check if all values in the dictionary are equal to 'n'.
# Print the result of the check.
print(value_check(students, n))

# Set the value 'n' to be checked to 10.
n = 10

# Print a message indicating the intention to check if all values in the dictionary are equal to 'n'.
print("\nCheck all are", n, "in the dictionary.")

# Call the 'value_check' function to check if all values in the dictionary are equal to 'n'.
# Print the result of the check.
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
