Answer 2

a=[1,2,3]

'a' here is a list.

It is mutable.

1) If a=[1,2,3]

If we will run a[1:2]=[4]

Then 'a' will become [1,4,3]

i.e, a=[1,2,3]

    a[1:2]=[4]

After this operation a=[1,4,3]

2) If a=[1,2,3]

If we will run a[1:1]=[4]

Then 'a' will become [1,4,2,3]

i.e, a=[1,2,3]

    a[1:1]=[4]

After this operation a=[1,4,2,3]

Lists :

• Ordered collection of data
• Are similar to string
• Way of creating the list : enclose the elements in square brackets []
• Eg1: l = [10,20,30,40]
• Eg2: l = ["hello",2.0,5,[10,20]]
