In this simple python program, we need to find the length of an array. It's an intermediate-level python program.
To understand this example, you should have knowledge of the following Python programming topics:
An array is a collection of elements of the same data type. In this array python program, we need to find the number of elements in an array. For example, consider an array A. with the values [1. 2. 3. 4. 5]In this simple python program, we need to count the number of elements and print the count as 5 using print in python programming functions. In python language, it supports functions or methods called
len() , which is a built-in method to find the length of the array. So we have to use that python method to find the length of the given array in the python language.
STEP 1: Initialize an array with some predefined values.
STEP 2: Use the print statement in the python programming language to print the number of elements in the array.
We use the
len() method, a built-in method in python, to get the count of the array elements. We also use the
str() function to convert the integer to string before printing the value.
arr = [1, 2, 3, 4, 5]; print("Number of elements in the array: " + str(len(arr)));
Number of elements in the array: 5
