Remove Null values from an array in Python

Remove Null Values from an array in Python:
  • Original Array:
    • 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)
