[issue25457] json dump fails for mixed-type keys when sort_keys is specified

2021-01-07 Thread naught101 


naught101  added the comment:

I want to do something like this:

hashlib.md5(json.dumps(d, sort_keys=True))

So I can check if a dict's contents are the same as a DB version, but I can't 
guarantee that all the keys are strings, so it breaks, annoyingly. I would very 
much like the apply-default-function-then-sort approach. Until then, my 
work-around is this:

def deep_stringize_dict_keys(item):
"""Converts all keys to strings in a nested dictionary"""
if isinstance(item, dict):
return {str(k): deep_stringize_dict_keys(v) for k, v in 
item.items()}

if isinstance(item, list):
# This will check only ONE layer deep for nested dictionaries 
inside lists.
# If you need deeper than that, you're probably doing something 
stupid.
if any(isinstance(v, dict) for v in item):
return [deep_stringize_dict_keys(v) if isinstance(v, dict) else 
v
for v in item]

# I don't care about tuples, since they don't exist in JSON

return item

Maybe it can be of some use for others.

[issue27873] multiprocessing.pool.Pool.map should take more than one iterable

It would be helpful if the docs at 
https://docs.python.org/3/library/multiprocessing.html#multiprocessing.pool.Pool.map
 and in `help(Pool.map)` mentioned starmap in a "see also" section at the 
bottom.

Happy to. What is the process? hg clone cpython, and make a patch from that and 
post it here? Or is there some pull-request style process available?

OK, one question, is Pool.map preferable to Pool.starmap in any particular 
cases?
