(In addition to @Coldspeed answer)
Look at the below examples:
words = ['cat', 'window', 'defenestrate']
words2 = words
words2 is words
results: True
It means names word and words2 refer to the same object.
words = ['cat', 'window', 'defenestrate']
words2 = words[:]
words2 is words
results: False
In this case, we have created the new object.
