# How to Find the Length of a List in Python

In this tutorial, we will program 'How to Find the Length of a List in Python'. We will learn how to check the total length of a list. The objective is to enable you to efficiently determine the length of a list. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for counting the total length in a list. I will do my best to provide you with the easiest way for getting the length So, let's start with the coding.

## Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.
`ret = False  while True:        print("\n================== Find the Length of a List ==================\n\n")        my_list = [1, 4, 5, 7, 8, 9, 12, 15]          print("The list is : " + str(my_list))          counter = 0         for i in my_list:                counter = counter + 1         print("\n")        print("The length of list is : " + str(counter))         opt = input("\nDo you want to try again?(yes/no): ")         if opt.lower() == 'yes':                ret=False        elif opt.lower() == 'no':                ret=True                print("Exiting program....")         else:                print("Please enter yes/no:")                break         if ret == False:                continue`

This Python script calculates the length of a predefined list my_list. It prints the list and then uses a for loop to count the number of elements in the list, incrementing a counter variable for each element. After calculating the length, it prints the length of the list. The script then asks the user if they want to try again or exit the program.
