I am using argparse with subparsers to do different actions. Each action has slightly different arguments.
I have set it up as the documentations instructs, with one action in subparser (parser_2) and the other subparser (parser_3) when i do help for usage of each it says the correct parameters
This is for cdf:
positional arguments:
repo name the repo to perform tasks on
optional arguments:
-h, --help show this help message and exit
--state {open,closed}
Print issues in a repository having status of
all(default), open, or closed
this is for clsiss:
usage: subparsprob.py clsiss [-h] repo issnums [issnums ...]
positional arguments:
repo name the repo to perform tasks on
issnums put the issue number(s) separated by blank
optional arguments:
-h, --help show this help message and exit
however when i actually run the commands i get usage errors: for clsiss executing from command line:
PS C:\xxx> python subparsprob.py clsiss repo 1
usage: subparsprob.py clsiss [-h] repo issnums [issnums ...]
subparsprob.py clsiss: error: argument issnums: invalid int value: 'repo'
for cdf (executing from command line):
PS C:\xxx> python subparsprob.py cdf repo
usage: subparsprob.py clsiss [-h] repo issnums [issnums ...]
subparsprob.py clsiss: error: argument issnums: invalid int value: 'repo'
please help, I am using the correct arguments and number of argument but cannot figure out why the usage is wrong when i actually try to run it
i am still getting the same error , here is the entire code, I cannot figure it out. Please help
#!/usr/bin/python3

With a copy-n-paste of your code:
1301:~/mypy$ python3 stack58684096.py -h
usage: stack58684096.py [-h] {clsiss,cdf} ...
Invoke various actions
positional arguments:
{clsiss,cdf} sub-commands for options
clsiss close issues
cdf create default tasks/issues
optional arguments:
-h, --help show this help message and exit
I don't get your errors:
1302:~/mypy$ python3 stack58684096.py clsiss repo 1
Namespace(action_name='clsiss', issnums=[1], repo='repo')
1302:~/mypy$ python3 stack58684096.py cdf repo
Namespace(action_name='cdf', repo='repo', state='all')
1302:~/mypy$ python3 stack58684096.py clsiss -h
usage: stack58684096.py clsiss [-h] repo issnums [issnums ...]
positional arguments:
repo name the repo to perform tasks on
issnums put the issue number(s) separated by blank
optional arguments:
-h, --help show this help message and exit
Your errors - sort of:
1302:~/mypy$ python3 stack58684096.py clsiss repo
usage: stack58684096.py clsiss [-h] repo issnums [issnums ...]
stack58684096.py clsiss: error: the following arguments are required: issnums
1304:~/mypy$ python3 stack58684096.py clsiss repo repo
usage: stack58684096.py clsiss [-h] repo issnums [issnums ...]
stack58684096.py clsiss: error: argument issnums: invalid int value: 'repo'
