list Data Type is used to represent group of values as a single entity where insertion order required to to preserve and duplicates are allowed then list data type is used.
1. insertion order is preserved.
2. duplicates are allowed.
3. heterogeneous objects are allowed.
4. values should be enclosed within square braces.
5. Growable in nature.
Example 1:
list=[10,10.5,’Webnoid’,True,10]
print(list)#[10,10.5,’Webnoid’,True,10]
Example 2:
list=[10,20,30,40]
>>>list[0]
10
>>>list[-1]
40
>>>list[1:3]
[20,30]
>>>list[0]=100
>>>for i in list:print(i)
…
100
20
30
40
list growable in nature based on our requirement size can be increased or decreased.
Example:
>>>list=[5,10,15]
>>>list.append(“Webnoid”)
>>>list
[5,10,15,’Webnoid’]
>>>list.remove(10)
>>>list
[5,15,’Webnoid’]
>>>list2=list*2
>>>list2
[5,15,’Webnoid’,5,15,’Webnoid’]
