v3: bool = False
@property
@computed_cached_property
def v4(self):
print('run code in v4 function')
return f'v1:{self.v1}, v2:{self.v2}, v3:{self.v3}'
@property
@computed_cached_property(typed=Ture)
# same as @functools.lru_cache(maxsize=1, typed=Ture)
def v5(self):
print('run code in v4 function')
return f'v1:{self.v1}, v2:{self.v2}, v3:{self.v3}'
a1 = A(v1=99)
print(a1.v4)
print(a1.v4)
a1.v2 = 'xxoo'
print(a1.v4)
# output
# run code in v4 function
# v1:99, v2:fuck, v3:False
# v1:99, v2:fuck, v3:False
# run code in v4 function
# v1:99, v2:xxoo, v3:False
