However, I want to know, how to get positional arguments with Click?

Something like this.
If nargs is set -1,then an unlimited number of arguments is accepted.

#numb_input.py
import click

@click.command()
@click.argument('n', nargs=-1)
def numbers(n):
    click.echo(n)
    click.echo(sum(int(i) for i in n))

if __name__ == '__main__':
    numbers()

Output:
(click) C:\Python36\click
λ python numb_input.py 1 2 3 4 5
('1', '2', '3', '4', '5')
15

(click) C:\Python36\click
λ python numb_input.py 100 458 96878
('100', '458', '96878')
97436

As a example sum first numbers,then make a dict of last argument.

#numb_input_1.py
import click

@click.command()
@click.argument('n', nargs=-1)
@click.argument('d', nargs=1)
def numbers(n, d):
    click.echo(sum(float(i) for i in n))
    to_dict = dict([d.split('=')])
    click.echo(to_dict)

if __name__ == '__main__':
    numbers()

Output:
(click) C:\Python36\click
λ python numb_input_1.py 100 458 96878 my_number=666
97436.0
{'my_number': '666'}
