When it is required to concatenate strings in a given order, a simple iteration is used.
Below is a demonstration of the same −
my_list = ["pyt", "fun", "for", "learning"] print("The list is :") print(my_list) sort_order = [1, 0, 3, 2] my_result = '' for element in sort_order: my_result += my_list[element] print("The result is :") print(my_result)
The list is : ['pyt', 'fun', 'for', 'learning'] The result is : funpytlearningfor
A list is defined and displayed on the console.
Another list of integers is defined, which is the order of sorting.
An empty string is created.
The sort order list is iterated over, and the element being iterated over is used as index to access elements from the string list.
This is appended to the empty string.
This is the output that is displayed on the console.
