When it is required to find the frequency of numbers greater than each element in a list, a list comprehension and the ‘sum’ method is used.
Below is a demonstration of the same −
Example
my_list = [24, 13, 72, 22, 12, 47]
print("The list is :")
print(my_list)
my_result = [sum(1 for element in my_list if index <= element) for index in my_list]
print("The result is :")
print(my_result)Output
The list is : [24, 13, 72, 22, 12, 47] The result is : [3, 5, 1, 4, 6, 2]
Explanation
A list of integers is defined and is displayed on the console.
A list comprehension is used to iterate over the elements of the list, and check if the index of every element is less than the element itself.
If so, it is added using the ‘sum’ method, converted to a list, and assigned to a variable.
This is displayed as output on the console.
