It returns the length of the DataFrame. The length is equal to thelast index+1. We will access this location and assign the list as a record to that location usingloc[len(df)]. Example Code: # Python 3.ximportpandasaspd student={"Name":["Jhon","Aliya","Nate","Amber"],"Course":...
append(x)Adds a single element to the end of the array. extend(iterable)Adds a list, array, or other iterable to the end of array. insert(i, x)Inserts an element before the given index of the array. The following example demonstrates how to create a new array object by joining two ...

When should you use Python's built-in list function to create a list? And when should you use square brackets ([...]) to create a new list instead? The list constructor is one of Python's built-in functions that is, strangely, frequently underused and overused. Let's take a look ...
