Python – Consecutive identical elements count
When it is required to get the count of consecutive identical elements in a list, an iteration, the ‘append’ method, and the ‘set’ method are used.
Example
Below is a demonstration of the same
my_list = [24, 24, 24, 15, 15, 64, 64, 71, 13, 95, 100]
print("The list is :")
print(my_list)
my_result = []
for index in range(0, len(my_list) - 1):
if my_list[index] == my_list[index + 1]:
my_result.append(my_list[index])
my_result = len(list(set(my_result)))
print("The result is :")
print(my_result)Output
The list is : [24, 24, 24, 15, 15, 64, 64, 71, 13, 95, 100] The result is : 3
Explanation
A list is defined and is displayed on the console.
An empty list is defined.
The list is iterated over and if the element in the zeroth index and element in the first index are equivalent, the zeroth element is appended to the empty list.
This is converted to a set and then to a list, and its length is assigned to a variable.
This is the output that is displayed on the console.
