I use API with long name of argument parameters. Consequently, I create following dictionaries for most common combinations of values which are then unpacked in function calls.
a_T = {'API parameter a': True}
a_F = {'API parameter a': False}
b_100 = {'API parameter b': 100}
b_0 = {'API parameter b': 0}
hello = {'API parameter c': 'hello'}
bye = {'API parameter d': 'goodbye'}
myf(**a_T, **bye)
myf(**b_0)
myf(**a_F, **b_100, **hello, **bye)
Is there any way to avoid repeat double asterisk? The code becomes quite unreadable with many of these strange characters.
Once could then add this unpacking utility to myf:
myf(a_T, bye)
myf(b_0)
myf(a_F, b_100, hello, bye)
You can actually use |
for Python 3.9+ to combine all the dictionaries then send unpacked version.
def fun(**kwargs):
print(kwargs)
>>> fun(**a_F| b_100| hello| bye)
{'API parameter a': False, 'API parameter b': 100, 'API parameter c': 'hello', 'API parameter d': 'goodbye'}
Or just use *args
and pass multiple dictionaries:
def fun(*args):
print(args)
>>> fun(a_F,b_100,hello,bye)
({'API parameter a': False}, {'API parameter b': 100}, {'API parameter c': 'hello'}, {'API parameter d': 'goodbye'})
Another solution is to use Python decorator and take care of ugly part inside the decorator function:
def decorator(fun):
def wrapper(*args):
from functools import reduce
kwargs = reduce(lambda a, b: a | b, args)
return fun(**kwargs)
return wrapper
@decorator
def main_fun(**kwargs):
print(kwargs)
>>> main_fun(a_F,b_100,hello,z)
{'API parameter a': False, 'API parameter b': 100, 'API parameter c': 'hello', 'parameter 4': 'goodbye'}
