![]() ![]() # The length of the list using the length_hint() method is: 7 Print("The length of the list using the length_hint() method is: " + str(sizeOfDemoList)) The example below shows you how to use the length_hint() method to get the length of a list from operator import length_hint: demoList = The syntax for using the len() method is length_hint(listName). Length_hint() is defined in the operator module, so you need to import it from there before you can use it. The length_hint() method is a less known way of getting the length of a list and other iterables. How to Get the Length of a List with the length_hint() Function # Output: The length of the list using the len() method is: 7 Print("The length of the list using the len() method is: " + str(sizeOfDemoList)) The code snippet below shows how to use the len() function to get the length of a list: demoList = The syntax for using the len() method is len(listName). This is more straightforward than using a for loop. Using the len() function is the most common way to get the length of an iterable. How to Get the Length of a List with the len() Function # Output: The length of the list using the naive method is: 7 Print("The length of the list using the naive method is: " + str(counter)) # Printing the result to the console by converting counter to string in order to get the number # Incrementing counter variable to get each item in the list The example below shows you how to use the naïve method to get the length of a list in Python demoList = This method is commonly called the naïve method. You can use the native for loop of Python to get the length of a list because just like a tuple and dictionary, a list is iterable. How to Get the Length of a List in Python with a For Loop In this article, I will show you how to get the length of a list in 3 different ways. To get the length of a list in Python, you can use the built-in len() function.Īpart from the len() function, you can also use a for loop and the length_hint() function to get the length of a list. With the help len() function we will write a program in a Python file in Ubuntu(Linux OS) to get the length of String.In Python, you use a list to store various types of data such as strings and numbers.Ī list is identifiable by the square brackets that surround it, and individual values are separated by a comma. The len() is the predefined function of Python which returns the length of a String, array, tuple or dictionary in a program. So the first method we are going to discuss is to find the length of String using len() function. RequirementsĪny version of Python should be installed on your system(Python3 is preinstalled in latest Ubuntu versions)īelow I have discussed different methods to get the length of String in Python, you can follow any of the method you find easier or appropriate for yourself: How to find Length of a String In Python Using len() Function ![]() So in this Article we will discuss the different ways to get the length of a String in Python on the Linux System. Sometimes we need to know the length of String which we are using in Python programs especially when String is provided by the user. Python is a Scripting language we can easily program in Python on Ubuntu System or any other Linux System and execute them without any extra effort.
