# Python – Sort List by Dictionary values

• Last Updated : 11 May, 2020

Sometimes while working with Python dictionary, we can have problem in which we need to perform a sort of list according to corresponding value in dictionary. This can have application in many domains, including data and web development. Lets discuss certain ways in which this task can be performed.

Method #1 : Using `sorted() + key + lambda`
The combination of above functions can be used to solve this problem. In this, we perform the task of sorting using sorted(). The lambda function is used to get key’s values.

 `# Python3 code to demonstrate working of ``# Sort List by Dictionary values``# Using sorted() + key + lambda`` ` `# initializing list``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# initializing Dictionary``test_dict ``=` `{``'gfg'` `: ``56``, ``'is'` `: ``12``, ``'best'` `: ``76``}`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Sort List by Dictionary values``# Using sorted() + key + lambda``res ``=` `sorted``(test_list, key ``=` `lambda` `ele: test_dict[ele])`` ` `# printing result ``print``(``"The list after sorting : "` `+` `str``(res)) `

Output :

```The original list is : ['gfg', 'is', 'best']
The original dictionary is : {'best': 76, 'gfg': 56, 'is': 12}
The list after sorting : ['is', 'gfg', 'best']
```

Method #2 : Using `sorted() + key + get()`
This method performs the task in similar way as above method. The difference is that it accesses values get().

 `# Python3 code to demonstrate working of ``# Sort List by Dictionary values``# Using sorted() + key + get()`` ` `# initializing list``test_list ``=` `[``'gfg'``, ``'is'``, ``'best'``]`` ` `# initializing Dictionary``test_dict ``=` `{``'gfg'` `: ``56``, ``'is'` `: ``12``, ``'best'` `: ``76``}`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# printing original dictionary``print``(``"The original dictionary is : "` `+` `str``(test_dict))`` ` `# Sort List by Dictionary values``# Using sorted() + key + get()``res ``=` `sorted``(test_list, key ``=` `test_dict.get)`` ` `# printing result ``print``(``"The list after sorting : "` `+` `str``(res)) `

Output :

```The original list is : ['gfg', 'is', 'best']
The original dictionary is : {'best': 76, 'gfg': 56, 'is': 12}
The list after sorting : ['is', 'gfg', 'best']
```
