Things I have tried but did not work:
parser.add_argument('--download',type=bool,default=False)parser.add_argument('--download',default=False,action='store_true')parser.add_argument('--download',action='store_true')
For case 1, Passing False also gets interpreted as True.
For case 2 and 3, I get the error
main.py: error: unrecognized arguments: False
Python version : 3.8
Why does argparse not work for boolean arguments?
>Solution :
The way ‘store_true’ works is that if you give --download as an argument, then the value is true; and if you omit it, it is false.
The reason type=bool doesn’t work as you want is that any nonempty string passed to the bool function will result in True. (You could, if you wanted, write a function that returns True if the string is "True" and False if it is "False", and use that for type, but that is not the typical use-case.)
