Use the filter() function to remove None from a list in Python. Other ways are the Naive Method and list comprehension.
Example remove None in Python
Simple example code deletes/drops none from the list in Python.
Using filter() function
This method checks for any None value in the list and removes them.
list1 = [1, None, 3, None, None, 6, 7, None] res = list(filter(None, list1)) print(res)
Naive Method iteration
Simply iterate through the whole list and append non-None values into a new list.
list1 = [1, None, 3, None, None, 6, 7, None] res =  for val in list1: if val is not None: res.append(val) print(res)
Output: [1, 3, 6, 7]
Using list comprehension
Same as the iterate method but with a sorter code. Just check for True values and filter without the None value list.
list1 = ["A", None, 3, None, None, 6, 7, None] res = [i for i in list1 if i] print(res)
Output: [‘A’, 3, 6, 7]
