How to add elements to one-dimensional array in python

An array is an ordered collection in which elements can be added and removed at any time. You can use the append() function to add new objects to the end of the array. You can also use the insert() function to insert a specified object into a specified position in the array.

1. append() function:

append() function syntax:

list.append(obj)

Parameters: obj -- the object added to the end of the list.

Return value: This method has no return value, but it will modify the original list.

The following example shows how to use the append() function:

aList = [123, 'xyz', 'zara', 'abc'];
aList.append( 2009 );
print "Updated List : ", aList;

The output results are as follows:

Updated List :  [123, 'xyz', 'zara', 'abc', 2009]

2. insert() function:

Syntax:

list.insert(index, obj)

Parameters:

index -- The index position where object obj needs to be inserted. obj – the object to be inserted into the list.

Return value: This method has no return value, but will insert the object at the specified position in the list.

The following example shows how to use the insert() function:

aList = [123, 'xyz', 'zara', 'abc'] 
aList.insert( 3, 2009) 
print "Final List : ", aList

Output result:

Final List : [123, 'xyz', 'zara', 2009, 'abc']
