You start with an array that contains some None values mixed with other elements.
Example: [1, None, 2, 3, None, 4, 5, None]
List Comprehension:
List comprehensions provide a concise way to create lists. They are generally more readable and faster than traditional for-loops.
Conditional Check:
Inside the list comprehension, you can add a condition to include only elements that are not None.
This is the starting array. It contains integers and None values.
[x for x in array]:
This part of the list comprehension creates a new list by iterating over each element (x) in the original array
if x is not Null:
This is a condition that filters out None values. It checks each element (x) and includes it in the new list only if it is not None.
This prints the new list, which now excludes all None values from the original array.
Program:
# Original array with some None values
array = [1, None, 2, 3, None, 4, 5, None]# Using list comprehension to remove None values
cleaned_array = [x for x in array if x is not None]print(cleaned_array)
