# Python – Numeric Sort in Mixed Pair String List

• Last Updated : 23 Jun, 2020

Sometimes, while working with data records, we can have a problem in which we receive data in custom format, and we need to perform a sort. We can receive both name of person and space-separated score and require to get the best to worst sorting. Lets discuss a way in which this particular problem can be solved.

Method #1 : Using `split() + sort()` + key function
The combination of above functionalities can be used to perform this task. In this, we perform a sort using external function in which we split the string and extract the numeric part.

 `# Python3 code to demonstrate  ` `# Numeric Sort in Mixed Pair String List ` `# using split() + sort() + key function ` ` `  `# helper function  ` `def` `helper_func(ele): ` `        ``name, val ``=` `ele.split() ` `        ``return` `int``(val) ` ` `  `# Initializing list ` `test_list ``=` `[``"Manjeet 5"``, ``"Akshat 7"``, ``"Akash 6"``, ``"Nikhil 10"``] ` ` `  `# printing original list ` `print``(``"The original list is : "` `+` `str``(test_list)) ` ` `  `# Numeric Sort in Mixed Pair String List ` `# using split() + sort() + key function ` `test_list.sort(key ``=` `helper_func, reverse ``=` `True``) ` `     `  `# printing result  ` `print` `(``"The reverse sorted numerics are : "` `+` `str``(test_list)) `

Output :

```The original list is : ['Manjeet 5', 'Akshat 7', 'Akash 6', 'Nikhil 10']
The reverse sorted numerics are : ['Nikhil 10', 'Akshat 7', 'Akash 6', 'Manjeet 5']
```

Method #2 : Using `split() + lambda + sorted()`
The combination of above methods can be used to perform this task. In this, we perform split on numbers as above. The difference is that it is one liner and use lambda function to perform.

 `# Python3 code to demonstrate  ` `# Numeric Sort in Mixed Pair String List ` `# using split() + sorted() + lambda ` ` `  `# Initializing list ` `test_list ``=` `[``"Manjeet 5"``, ``"Akshat 7"``, ``"Akash 6"``, ``"Nikhil 10"``] ` ` `  `# printing original list ` `print``(``"The original list is : "` `+` `str``(test_list)) ` ` `  `# Numeric Sort in Mixed Pair String List ` `# using split() + sorted() + lambda ` `res ``=` `sorted``(test_list, reverse ``=` `True``, key ``=` `lambda` `ele: ``int``(ele.split()[``1``])) ` ` `  `# printing result  ` `print` `(``"The reverse sorted numerics are : "` `+` `str``(res)) `

Output :

```The original list is : ['Manjeet 5', 'Akshat 7', 'Akash 6', 'Nikhil 10']
The reverse sorted numerics are : ['Nikhil 10', 'Akshat 7', 'Akash 6', 'Manjeet 5']
```
