How Can I Copy An Immutable Object Like Tuple In Python?

copy.copy() and copy.deepcopy() just copy the reference for an immutable object like a tuple. How can I create a duplicate copy of the first immutable object at a different memory

Solution 1:

You're looking for deepcopy.

from copyimport deepcopy

tup = (1, 2, 3, 4, 5)
put = deepcopy(tup)

Admittedly, the ID of these two tuples will point to the same address. Because a tuple is immutable, there's really no rationale to create another copy of it that's the exact same. However, note that tuples can contain mutable elements to them, and deepcopy/id behaves as you anticipate it would:

from copyimport deepcopy
tup = (1, 2, [])
put = deepcopy(tup)
tup[2].append('hello')
print tup # (1, 2, ['hello'])
print put # (1, 2, [])

Solution 2:

Add the empty tuple to it:

>>>a = (1, 2, 3)>>>a is a+tuple()  
False

Concatenating tuples always returns a new distinct tuple, even when the result turns out to be equal.

Solution 3:

try this:

tup = (1,2,3)
nt = tuple(list(tup))

And I think adding an empty tuple is much better.
