# Python | Minimum value keys in Dictionary

Many times, we may have problem in which we require to find not just the value, but the corresponding keys to the minimum value in the entire dictionary. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using min() + list comprehension + values()
The combination of above functions can be used to perform this particular task. In this, minimum value is extracted using the `min` function, while values of dictionary is extracted using `values()`. The list comprehension is used to iterate through the dictionary for matching keys with min value.

 `# Python3 code to demonstrate working of``# Finding min value keys in dictionary``# Using min() + list comprehension + values()`` ` `# initializing dictionary``test_dict ``=` `{``'Gfg'` `: ``11``, ``'for'` `: ``2``, ``'CS'` `: ``11``, ``'geeks'``:``8``, ``'nerd'``:``2``}`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Using min() + list comprehension + values()``# Finding min value keys in dictionary``temp ``=` `min``(test_dict.values())``res ``=` `[key ``for` `key ``in` `test_dict ``if` `test_dict[key] ``=``=` `temp]`` ` `# printing result ``print``(``"Keys with minimum values are : "` `+` `str``(res))`

Output:

The original dictionary is : {‘nerd’: 2, ‘Gfg’: 11, ‘geeks’: 8, ‘CS’: 11, ‘for’: 2}
Keys with minimum values are : [‘nerd’, ‘for’]

Method #2 : Using `all()` + list comprehension
This task can also be performed using list comprehension and all function. In this, we take all the elements values, using `all` function that are greater than values with keys and return the keys with smallest values using list comprehension.

 `# Python3 code to demonstrate working of``# Finding min value keys in dictionary``# Using all() + list comprehension`` ` `# initializing dictionary``test_dict ``=` `{``'Gfg'` `: ``1``, ``'for'` `: ``2``, ``'CS'` `: ``1``}`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Using all() + list comprehension``# Finding min value keys in dictionary``res ``=`  `[key ``for` `key ``in` `test_dict ``if` `        ``all``(test_dict[temp] >``=` `test_dict[key]``        ``for` `temp ``in` `test_dict)]`` ` `# printing result ``print``(``"Keys with minimum values are : "` `+` `str``(res))`

Output:

The original dictionary is : {‘Gfg’: 1, ‘CS’: 1, ‘for’: 2}
Keys with minimum values are : [‘Gfg’, ‘CS’]
