Python list length: How to Observe a Length of List
To find the length of a list in Python, use the len() method. The len() is a built-in Python method that takes a total number of elements in the list and returns the length of a list. The len() method can be used with a listing, tuple, arrays, dictionary, etc.
A list data type is used to store the sequence of various types of data. A list is defined as a collection of values or elements of unlike types. The elements in the list are separated with a comma(,) and surrounded with the square brackets [ ].
The len() method is i of the nigh used and convenient ways to observe the length of a list in Python.

How to Get Length of an Array in Python

from array import array arr_len = array('b',[11, nineteen, 21, 18, 46]) print("Number of elements in an Assortment:", len(arr_len)) Output
