[issue29626] Issue with spacing in argparse module while using help

[Falguniben Jhaveri]

Falguniben Jhaveri added the comment:

There is an extra spacing here if you look carefully. I have commented
above the code. Similarly it happens for "-o" too but not for other
alphabets.

1427:~/mypy/argdev$ python3 issue29626.py delete -h
usage: cli delete [-h] [-p] userid

Deletes a user in your organization.

positional arguments:
  userid The userid of user.

optional arguments:
  -h, --help show this help message and exit
// extra space after p and ",".
  -p , --projectid   Specify the project ID of project from where you want
to
 delete the user or else user will be deleted from
 organization.

I saw this issue as I use argparse for my CLI usecase which has nested
commands.

Sample code to repro this:

import argparse

parser = argparse.ArgumentParser(prog='cli')
subparsers = parser.add_subparsers(dest="command")

subparsers_user_delete = subparsers.add_parser("delete", help="Deletes a 
user in your organization.",
description="Deletes a 
user in your organization.")
subparsers_user_delete.add_argument("userid", help="The userid of user.", 
default=None, type=int)
subparsers_user_delete.add_argument("-p", "--projectid", metavar="",
help="Specify the project ID of project 
from where you want to delete"
 " the user or else user will be 
deleted from organization.", type=int,
default=None)

parser_nodes = subparsers.add_parser('nodes')
sp = parser_nodes.add_subparsers()
p1 = sp.add_parser('list', description='Lists nodes in your current 
project')
p1.add_argument('-p', '--projectid', action='store_true')
p1.add_argument('-o', '--org', action='store_true', help=' (For 
administrators only) Lists all the nodes in')
parser.parse_args()

Please run following command:
$issue.py delete -h

[issue29626] Issue with spacing in argparse module while using help

[Falguniben Jhaveri]

New submission from Falguniben Jhaveri:

When I use argparse the optional arguments with character "-p" and "-s" has 
improper spacing while using help/usage command.

Sample out put from argparse module:

usage: cli node list [-h] [-p] [-o]

Lists nodes in your current project.

optional arguments:
  -h, --help show this help message and exit
  // extra space after p
  -p , --projectid  
  -o, --org (For administrators only) Lists all the nodes in
