New submission from Demid :
There is a possibility that someone (like me) accidentally will omit
parentheses with FileType arguments after FileType, and parser will contain
wrong file until someone will try to use it.
Example:
parser = argparse.ArgumentParser()
parser.add_argument(&#x

Demid added the comment:
If you will run `python test.py hello.txt, where test.py is:
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('echo', type=argparse.FileType)
args = parser.parse_args()
print(args.echo)
You will receive:
FileType('hello.txt'
Demid added the comment:
What if I will add mode check in FileType.__init__?
