The previously Python console shows that an empty list with 5 placeholders has been created successfully. Needless to say, you can also use emptystring""number zero0, or something else as placeholder. It is up to your choice. Let’s now check the other option!
Empty Note that this method is considered a little slow but also works with a numpy array, whereas the if not method fails with numpy arrays.Use an Empty List [] to Check if a List Is Empty or Not in PythonThis is an unconventional method and is not used very frequently, but still,...
Using the reverse() method to reverse a list Thereverse()method is a built-in Python function that modifies the original list directly. This is an in-place reversal, meaning it does not create a new list. Instead, it reorders the existing list's elements in reverse. ...
In Python, tuples are an immutable data structure that allows you to store multiple values in a single variable. While they are often used for grouping related data, tuples also offer the flexibility to return multiple values from a function. ...
What causes the “List Index Out of Range” error? As Python uses zero-based indexing, when you try to access an element at an index less than 0 or greater than or equal to the list’s length, Python tells you via this error that the specified index is out of the permissible bounds...
In summary, Python provides a simple way to reverse a list by making use of the functionreversed(). You also can reverse a list manually by looping it in afororwhileloop. Python also has an easy method of reversing a list in a single line if you are comfortable using the slice operato...

Coming to the user-defined function, we have passed the number of zeros we want in the list to the function call. The repeat function of the itertools module is used to return an object based on a condition.ReferencesLearn more about Itertools here....
