2. Get the Length of Array using len() Function in Python Pythonlen()is abuilt-infunction, which is used to get the total number of elements present in the given array. It returns a count of the index that is one more than the number of elements present in the array. ...
The Pythonoperatormodule has alength_hint()method to estimate the length of a given iterable object. If the length is known, thelength_hint()method returns the actual length. Otherwise, thelength_hint()method returns an estimated length. For lists, the length is always known, so you would ...
The Pythonoperatorlibrary contains a method calledlength_hint()for estimating the length of iterable objects. The method returns the exact length of lists and objects with a known length. Alternatively, it provides the estimated length. To use thelength_hint()function, import the method from theo...
