Program to copy all elements of one array into another array

What is an Array ?

An array is defined as a collection of items that are stored at contiguous memory locations. It is a container which can hold a fixed number of items, and these items should be of the same type.

Source code :

     
arr1 = [1, 2, 3, 4, 5];     
     
    
arr2 = [None] * len(arr1);    
     
    
for i in range(0, len(arr1)):    
    arr2[i] = arr1[i];     
     
     
print("Elements of original array: ");    
for i in range(0, len(arr1)):    
   print(arr1[i]),    
     
print();    
     
print("Elements of new array: ");    
for i in range(0, len(arr2)):    
   print(arr2[i]),

Source code Explanation :

step 1: Initialize array
arr1 = [1, 2, 3, 4, 5];
step 2: Create another array arr2 with size of arr1
arr2 = [None] * len(arr1);
step 3: Copying all elements of one array into another
for i in range(0, len(arr1)):
arr2[i] = arr1[i];
step 4: Displaying elements of array arr1
print(“Elements of original array: “);
for i in range(0, len(arr1)):
print(arr1[i]),
print();
step 5:Displaying elements of array arr2
print(“Elements of new array: “);
for i in range(0, len(arr2)):
print(arr2[i]),

Output :

Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 19:29:22) [MSC v.1916 32 bit (Intel)] on win32
