find the length of an array in python

arr_len =len(arr)

This simple line of code finds the length of an array in Python. The keyword ‘len’ is used to find the length of any given object. In this example, the argument of the len() method is ‘arr’, which represents an array of any size. The result of the len() method is stored in the ‘arr_len’ variable, which can be used in other code. Once the len() method is called and the arr_len variable is set, the code can be used any number of times to find the length of the ‘arr’ array whenever needed.
