Identify all instances of a specific element in a Python list and return their indexes.
In Python, there are situations where it's required to locate every occurrence of a particular element within a list and return their corresponding indexes. Your task is to create a function that achieves this objective. ### Parameters - `lst` (List): This is the list consisting of either string or numerical elements. - `el` (str, int): This element is the one that's being searched for within the `lst`. ### Return Value - The function should return a list that contains the indexes of each occurrence of `el` within `lst`. ### Examples ```python # 'a' can be found at indexes 0, 1, 3, and 5 find_indexes(["a", "a", "b", "a", "b", "a"], "a") # Returns: [0, 1, 3, 5] # Number 5 can be found at indexes 1 and 2 find_indexes([1, 5, 5, 2, 7], 5) # Returns: [1, 2] # The list does not contain the number 8 find_indexes([1, 5, 5, 2, 7], 8) # Returns: [] ```
