Python> list> 3 copy methods> .copy () / list () / [:]> Works on Python3 / Error with .copy () on Python2> All were shallow copy

@ Introducing Python: Modern Computing in Simple Packages by Bill Lubanovic (No. 1424 / 12833)

There seem to be three ways to copy the list.

I've tried.

a = [ 'I am clone ' ]
b = a.copy()
c = list(a)
d = a[:]
 
a = [ 'I am original']
print(a)
print(b)
print(c)
print(d)

Python 3

result

['I am original']
['I am clone ']
['I am clone ']
['I am clone ']

Python 2

result

Traceback (most recent call last):
  File "prog.py", line 2, in <module>
AttributeError: 'list' object has no attribute 'copy'

docs

Python 3 https://docs.python.org/3.6/tutorial/datastructures.html

Python 2 https://docs.python.org/2/tutorial/datastructures.html

Python 3 has a description of list.copy (), Python 2 does not.

Additional learning

As @shiracamus comment, all the above copies were shallow copies.
