Verifying the Truthfulness of All Values in a Python Dictionary

We loop through each key and set it to false if we encounter the first instance of a false value, then exit the loop. It’s important to note that if the dictionary is empty, then the result will be that all values are equal to an empty string.

Solution 1:

var allValuesAreTrue = customDicationary.Values.All(value => value);

Observe that the output is


only when there are no elements in the dictionary, since in such cases, all the values are equivalent to



Solution 2:

Utilizing Linq is an option for achieving this. You can examine the dictionary’s values and proceed depending on the quantity of true/false responses received.

public void Program()
    var customDictionary = new Dictionary();
    customDictionary.Add("Apples are red", true);
    customDictionary.Add("Oranges are green", false);
    customDictionary.Add("Carrots are orange", true);
    bool allTrue = CheckDictionary(customDictionary);
    if(allTrue == true)
        Console.Write("All True");
        Console.Write("At least one false");
public bool CheckDictionary(Dictionary dictToCheck)
    var test = dictToCheck.Where(x => x.Value == false);
    if (test.Count() == 0)
        return true;
        return false;

Output: At least one false

Solution 3:

int counter = 0;
foreach (bool v in dic.Values)
    if (v) counter++;
return dic.Count == counter;
