I have a problem regarding args parameter of ArgumentParser.parse_args.

For example:
-------------------------------------
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("--boolean", type=bool)
parsed_args = parser.parse_args(["--boolean=''"])
--------------------------------------

results in parsed_args.boolean evaluate to True.
While i understand why this is happening (inner call of bool("''") evaluates to True), i don't know if that is an expected behavior.
If we look from console argument pass perspective with the example altered:
test.py
-------------------------------------
import argparse
parser = argparse.ArgumentParser()
parser.add_argument("--boolean", type=bool)
parsed_args = parser.parse_args()
--------------------------------------

If i now call:

python test.py --boolean=""

parsed_args.boolean will evaluate to False.
