How to remove empty elements from a list in Python - Using list comprehension, the filter() function, or a for loop - Tutorial with examples
if we have a list with elements[1, 2, 3]and another list with elements[4, 5, 6]. If we concatenate both the lists, then, the result may be[1, 2, 3, 4, 5, 6]or[4, 5, 6, 1, 2, 3]based on the order we concatenate. ...
To get the number of elements in a list in Python, you can use the len() function. Here's an example: my_list = [1, 2, 3, 4] num_elements = len(my_list) print(num_elements) # Output: 4 Try it Yourself » Copy Watch a video course Python - The Practi...
To store the unique elements in the new list that you created previously, simply traverse through all the elements of the given list with the help of a for loop and then check if each value from the given list is present in the list “res“. If a particular value from the given list ...
As the loop goes through the elements in the list, the counter increments by one each time. The final value of the counter is the list length. Method 2: len() Python offers a built-in method to find the length of a list calledlen(). This method is the most straightforward and common...

Python tuples are immutable. Meaning you cannot change them after they are created. So, you cannot append any element directly to a tuple.However, you can concatenate elements by creating a new tuple that combines the original and new elements. It is a copy operation, not a modification in...
