We basically iterate over the list and return an empty string if the item of the current iteration is None, otherwise we return the item as is. You can use this approach to replace None values with any other value. # Replace None values in a List using a for loop Alternatively, you ca...
Write a Python program to remove duplicates from a list. Visual Presentation: Sample Solution: Python Code: # Define a list 'a' with some duplicate and unique elementsa=[10,20,30,20,10,50,60,40,80,50,40]# Create an empty set to store duplicate items and an empty list for unique it...
If the function applied to an empty list, it does not raise any error. Conclusion It is up to your discretion to use the way of removing elements from a list, either by value or index. Different circumstances require a different approach, therefore Python provides various methods of removing...
To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
