Python copy of List

We need to copy a list, we can use a special method, today to the people said.

I'll define a list first.

A=[1,2,34]

I then use the built-in method ID () to see the address of the object

Print ID (a)

Object Address: 11488352

Then I copy a list of a and copy it to variable B.

b = a[:]

I'm outputting the variable b here.

Print B

The result is [1, 2, 34], and a is the same, and then I look at the address of table B below.

Print ID (b)

Object Address: 11511448

As you can see, the address of 2 objects is different, which means that a new list object is re-copied, not a reference assignment.
