# Python – Check if all values are K in dictionary

• Last Updated : 17 Dec, 2019

While working with dictionary, we might come to a problem in which we require to ensure that all the values are K in dictionary. This kind of problem can occur while checking status of start or checking for a bug/action that could have occurred. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using `all()` + dictionary comprehension
The combination of above functions can be used to perform the following task. The` all` function checks for each key and dictionary comprehension checks for the K value.

 `# Python3 code to demonstrate working of``# Test if all values are K in dictionary``# Using all() + dictionary comprehension`` ` `# Initialize dictionary``test_dict ``=` `{``'gfg'` `: ``8``, ``'is'` `: ``8``, ``'best'` `: ``8``}`` ` `# Printing original dictionary ``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Initialize K ``K ``=` `8`` ` `# using all() + dictionary comprehension``# Test if all values are K in dictionary``res ``=` `all``(x ``=``=` `K ``for` `x ``in` `test_dict.values())`` ` `# printing result ``print``(``"Does all keys have K value ? : "` `+` `str``(res))`
Output :

```The original dictionary is : {'gfg': 8, 'best': 8, 'is': 8}
Does all keys have K value ? : True
```

Method #2 : Using loop
This problem can be solved using brute force strategy using loop and we equate each key with K and return True if all elements match K.

 `# Python3 code to demonstrate working of``# Test if all values are K in dictionary``# Using loop`` ` `# Initialize dictionary``test_dict ``=` `{``'gfg'` `: ``8``, ``'is'` `: ``8``, ``'best'` `: ``8``}`` ` `# Printing original dictionary ``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Initialize K ``K ``=` `8`` ` `# using loop``# Test if all values are K in dictionary``res ``=` `True` `for` `key ``in` `test_dict:``    ``if` `test_dict[key] !``=` `K:``        ``res ``=` `False`` ` `# printing result ``print``(``"Does all keys have K value ? : "` `+` `str``(res))`
Output :
```The original dictionary is : {'gfg': 8, 'best': 8, 'is': 8}
Does all keys have K value ? : True
```
