slots=ArrayType() 4
slots=[4,6,9,2] 6
i=0 9
for i in range(3): 2
print data[i]

for i in range(3): None
print data[i] 3
print ("Array_deletion :") Array_deletion :

print data[i]

List : Creation , Appending .
>>># list creation:
>>>data=[1,2,3,4]
>>>data
>>>[1,2,3,4]
>>># list appending (add at last index)
>>>data.append(10)
>>>data
>>>[1,2,3,4,10]

List : Extending .
>>>A=[1,2,3,4]
>>>B=[5,6,7,8]
>>>A.extend(B)
>>>A
>>>[1,2,3,4,5,6,7,8]

List : Insertion .
>>>data=[1,2,3,4]
>>>data
>>>[1,2,3,4]
>>># list insertion (add value at certain index)
>>>data.insert(0,10)
>>>data
>>>[10,1,2,3,4]

List : Deleting .
>>>data=[1,2,3,4]
>>>data
>>>[1,2,3,4]
>>>#list deletion:(delete value from certain index )
>>>data.pop(1)
>>>data
>>>[1,3,4]

List : Deletion .
>>>data=[1,2,3,4]
>>>data
>>>[1,2,3,4]
>>>#list:delete value from last index)
>>>data.pop()
>>>data
>>>[1,2,3]

List : Slices .
>>>data=[2,4,6,8,10,12]
>>>aSlice=data[0:2]
>>>data
>>>[2,4,6,8,10,12]
>>>aSlice
>>>[2,4]
>>>aSlice=data[2:5]
>>>aSlice
>>>[6,8,10]
