Argparse tutorial example doesn't work in windows command line

Question

So I'm trying to teach myself how to use the python library argparse via the tutorial here . The example is given by the following piece of code which is saved as tut.py .

import argparse

parser = argparse.ArgumentParser(description='Process some integers.')
parser.add_argument('integers', metavar='N', type=int, nargs='+',
                help='an integer for the accumulator')
parser.add_argument('--sum', dest='accumulate', action='store_const',
                const=sum, default=max,
                help='sum the integers (default: find the max)')

args = parser.parse_args()
print(args.accumulate(args.integers))

In the tutorial they put a $ before every command in the command line which is due to them using Linux I think. First if I add an $ in my windows command line before any command I get the error

The "$" command was either misspelled or could not be found.

If I then run

 python tut.py 1 2 3 4

I don't get an error but neither is any output displayed in the command line. What would be expected is the sum of those integers though.

How can I make the output show up in the command prompt?

Answer 1

At the beginning I didn't think that it was important to specify that I use the anaconda distribution for python, however it turns out that using the anaconda command prompt instead of the windos 10 one solves the problem.

Output

(base) C:\Users\Admin\Desktop\HiWi\Codect>python tut.py 1 2 3 4
4

(base) C:\Users\Admin\Desktop\HiWi\Codect>python tut.py 1 2 3 4 --sum
10

(base) C:\Users\Admin\Desktop\HiWi\Codect>

Answer 2

Use this code to get some of n passed arguments: tut.py

import argparse

parser = argparse.ArgumentParser(description='Process some integers.')
parser.add_argument('integers', metavar='N', type=int, nargs='+',
                help='an integer for the accumulator')
parser.add_argument('--sum', dest='accumulate', action='store_const',
                const=sum, default=max,
                help='sum the integers (default: find the max)')

args = parser.parse_args()
print(sum(args.integers))

OUTPUT

python tut.py 1 2 3 4   
10

Note: when I run your code it runs perfectly
