• My post explains a frozenset (1).

symmetric_difference() can return the zero or more elements which the set or frozenset has but other doesn't have or which the set or frozenset doesn't have but other has as shown below:

*Memo:

• The 1st argument is other(Required-Type:Iterable):
  • Don't use other=.
• symmetric_difference() creates a copy.
• ^ can do symmetric_difference(), creating a new set or frozenset and supporting set and frozenset.

<Set>:

A = {10, 20, 30, 40}        # set
B = frozenset([10, 30, 50]) # frozenset
C = [30, 40]                # list

print(A.symmetric_difference(B)) # {40, 50, 20}
print(A.symmetric_difference(C)) # {10, 20}

A = {10, 20, 30, 40}        # set
B = frozenset([10, 30, 50]) # frozenset
C = frozenset([30, 40])     # frozenset

print(A ^ B) # {40, 50, 20}
print(A ^ C) # {10, 20}

<Frozenset>:

A = frozenset([10, 20, 30, 40]) # frozenset
B = {10, 30, 50}                # set
C = [30, 40]                    # list

print(A.symmetric_difference(B)) # frozenset({40, 50, 20})
print(A.symmetric_difference(C)) # frozenset({10, 20})

A = frozenset([10, 20, 30, 40]) # frozenset
B = {10, 30, 50}                # set
C = {30, 40}                    # set

print(A ^ B) # frozenset({40, 50, 20})
print(A ^ C) # frozenset({10, 20})

symmetric_difference_update() can return the zero or more elements which the set has but other doesn't have or which the set doesn't have but other has as shown below:

*Memo:

• The 1st argument is other(Required-Type:Iterable):
  • Don't use other=.
• symmetric_difference_update() doesn't create a copy.
• symmetric_difference_update() doesn't exist for a frozenset.
• ^= can do symmetric_difference_update(), creating a new set or frozenset and supporting set and frozenset.

<Set>:

A = {10, 20, 30, 40}        # set
B = frozenset([10, 30, 50]) # frozenset
C = [30, 40]                # list

A.symmetric_difference_update(B)
print(A)
# {40, 50, 20}

A.symmetric_difference_update(C)
print(A)
# {50, 20, 30}

A = {10, 20, 30, 40}        # set
B = frozenset([10, 30, 50]) # frozenset
C = frozenset([30, 40])     # frozenset

A ^= B
print(A)
# {40, 50, 20}

A ^= C
print(A)
# {50, 20, 30}

<Frozenset>:

A = frozenset([10, 20, 30, 40]) # frozenset
B = {10, 30, 50}                # set
C = {30, 40}                    # set

A ^= B
print(A)
# frozenset({40, 50, 20})

A ^= C
print(A)
# frozenset({50, 20, 30})
