list:

If you want to represent group of object as a single entity where duplication's are allowed and insertion order also preserved then we should go for list.

list : []  = Square bracket indicates list.

Example : l=[]
                type(l)
           output:list

l.append (12)
l.append(13)
l.append(15)
l.append(20)
print(l)
output: 12,13,15,20

l.append('govind')
output: 12,13,15,20,govind

l.append(None)

output: 12,13,15,20, govind, None

l[-1]
output : None
l[-2]
output: govind
l[1:5] 
output:3,4,5



Features :  Insertion order preserved
                 Duplication allowed
                 Allowed Heterogeneous data
                 Growable In Nature
                Values should be enclosed in Bracket []

l=[10,"govind",True,12.12]
l1=l12
output : 10 "govind" True,12.12 10 "govind" True 12.12
