Title: Resolving "TypeError: sort() got an unexpected keyword argument 'key'" in Python
Introduction:
Sorting is a common operation in programming, and Python provides a built-in sort() method to sort lists. However, you may encounter an error message like "TypeError: sort() got an unexpected keyword argument 'key'" when using the sort() method with the key parameter. In this tutorial, we will explore the cause of this error and demonstrate how to resolve it.
Understanding the Error:
The sort() method in Python allows you to specify a custom sorting key using the key parameter. This key is a function that takes an element from the iterable and returns a value to use for sorting. The error "TypeError: sort() got an unexpected keyword argument 'key'" occurs when you mistakenly try to use the key parameter with a method that doesn't support it.
Example:
In this example, we are trying to sort the list of numbers based on whether they are even or odd. However, the sort() method does not support the key parameter, leading to the mentioned error.
Resolution:
To resolve this issue, you should use the sorted() function instead of the sort() method when you need custom sorting with the key parameter.
Updated Example:
In this corrected example, we use the sorted() function with the key parameter to achieve the desired custom sorting.
Conclusion:
When encountering the "TypeError: sort() got an unexpected keyword argument 'key'" in Python, remember that the sort() method does not support the key parameter. To perform custom sorting, use the sorted() function instead. This tutorial has provided an understanding of the error, along with a corrected example demonstrating the use of the sorted() function for custom sorting.
