[issue38909] module name 'stat.py'

[da-dada]

New submission from da-dada :

well, call your module 'stat.py' and python takes over full ownership: it's 
somewhat all public..

[issue38998] dict.setdefault (setdefault of dictionary)

[da-dada]

New submission from da-dada :

from the docu I expected at the second call just a return of value and not a 
second calculation: there is room for improvement, as Elon Musk would say..

class Ddefault:

def __init__(self):
vars(self).setdefault('default', self.set_default())
vars(self).setdefault('default', self.set_default())

def set_default(self):
print(vars(self))
return 'default'

if __name__ == "__main__":
Ddefault()

[issue38998] dict.setdefault (setdefault of dictionary)

[da-dada]

da-dada  added the comment:

I have no problem of making my programme run properly (asking first if in dict 
etc), but I just read the docu of dict.setdefault

setdefault(key[, default]) 
If key is in the dictionary, return its value. If not, insert key with a value 
of default and return default. default defaults to None.

and it clearly reads if the key is.. return its value, with a full stop;
so either the docu is wrong (but proposes exactly the needed shortcut) or 
python is as it is: come in & find out

[issue38998] dict.setdefault (setdefault of dictionary)

[da-dada]

da-dada  added the comment:

my use case is different (I do a loop), but what I expected from the docs (just 
for fun!)

class Ddefault:

def __init__(self):
vars(self).setdefault('default', self.set_default() if not 'default' in 
vars(self) else self.default)
vars(self).setdefault('default', self.set_default() if not 'default' in 
vars(self) else self.default)
print(vars(self))

def set_default(self):
print(vars(self))
return 'default'

if __name__ == "__main__":
Ddefault()

may be the coding diverted from the docs after the fixing of issue 13521 and no 
one dares correcting..
anyway, I will probably keep my old coding (performance, if there is any)
