I have this code:
def curry_explicit(function, arity):
"""
Turning a function from several parameters into a function from one parameter that returns a function from the other parameters:
function(a,b) --> function(a)(b)
"""
if arity == 0:
return function
def get_args(args):
if len(args) == arity:
return function(*args)
def curry(x):
return get_args([*args, x])
return curry
return get_args([])
user_function = max
curried_function = curry_explicit(user_function, 3)
print(curried_function.__name__)
curry
I need the name curried_function to match the name of the function that we curried:
print(curried_function.__name__)
max
Maybe i can use functools wraps? But how?
You could do:
def curry_explicit(function, arity):
"""
Turning a function from several parameters into a function from one parameter that returns a function from the other parameters:
function(a,b) --> function(a)(b)
"""
if arity == 0:
return function
def get_args(args):
if len(args) == arity:
return function(*args)
def curry(x):
func = get_args([*args, x])
return func
curry.__name__ = function.__name__
return curry
return get_args([])
But honestly not sure if there are consequences to doing this. The functools library probably has a good solution (likely using the @wraps decorator as you suggested or something similar).
