So the rule of thumb for default argument value is "No mutable"
Cheers,
It can be used to store some variables from one call of
a function to an other one.
def test( _store={'x':0}):
x = _store['x']
..... do some stuff
_store['x'] = x
For personal dirty scripts, possibly, for all other situations, never.
not so dirty in my opinion
Especially since there's nothing in the code above that cannot be solved using
standard idioms .
Yes, putting _store dictionnary outside
_store={'x':0}
def test( ):
x = _store['x']
..... do some stuff
_store['x'] = x
or using a global variable, but you pollute in both case
the global scope unnecessary.
That is if you care about anyone reading your code ;)
