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...
Here, we will write a Python program where we will find the length of the list. We will see different ways to perform the task.
Using thelength_hint()method to get the length of a list 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 leng...

Now that the example list has been created, we will look at examples of how to get its length.Example 1: Get Length of List Using len() FunctionIn this first example, we will use Python’s len() function to find the length of the list:...
Python len() method is used to find the length of an array. As we all know, python does not support or provide us with the array data structure in a direct way. Instead, python serves with three different variations of using an array data structure. In this tutorial, we will learn ...
Python – Find Length of a Set To find the length of a Set in Python, you can call Python built-in function len() and pass the set as argument to the function. len() function returns an integer representing the number of elements in the Set. ...
To find the length of a string in Python, use len() function. We can also use For loop to iterate through each element and find the length of the string.
Python – Length of Range To find the length of a range in Python, call len() builtin function and pass the range object as argument. len() function returns the number of items in the range. Reference –Python len() builtin function ...
print("Length of an array:", len(arr)) Yields below output. 2.1 Get Length of 2-D Array in Python You can also use the Python len() function to compute the length of a 2-D array. Before going to calculate the length of the 2-D array we need to find the number of rows and ...
