New submission from Mat Leonard <[email protected]>:
Unicode symbols used as function arguments aren't preserved in the variable
names available from .__code__.co_varnames. Example shown below.
def func(ϵ, α, γ, ϕ):
pass
varnames = func.__code__.co_varnames
print(varnames)
print('ϵ' == varnames[0])
print('α' == varnames[1])
print('γ' == varnames[2])
print('ϕ' == varnames[3])
>> ('ε', 'α', 'γ', 'φ')
>> False
>> True
>> True
>> False
I wrote some code dependent on using function arguments obtained from
.__code__.co_varnames in a dictionary. Since the unicode arguments aren't
preserved from defining the function and .__code__.co_varnames, the lookup in
the dictionary fails.
Looks like same thing happens with the inspect module (maybe
.__code__.co_varnames comes from inspect)
inspect.signature(func)
>> <Signature (ε, α, γ, φ)>
