How to convert a `lambda` object to a` function` object in Python?

I've dealt with bugs regarding functions lambda

and their inability to be pickled

. I often use lambda

on-the-fly functions as disposable functions of use, and this dramatically reduces the productivity of my workflow when I have to individually recreate simple lambda functions in functional form for use with etching.

Is there a way to convert lambda

and all its arguments to an object function

in Python 3.6.1

?

lambda_func = lambda x: x.split(" ")
def func(x):
    return x.split(" ")
input_string = "Darth Plagueis was a Dark Lord of the Sith"

# Function Version
func(input_string)
# ['Darth', 'Plagueis', 'was', 'a', 'Dark', 'Lord', 'of', 'the', 'Sith']
lambda_func(input_string)
# ['Darth', 'Plagueis', 'was', 'a', 'Dark', 'Lord', 'of', 'the', 'Sith']

def lambda2func(lambda_func):
    #...
    return func_version
