parseopt with negative numbers as positional arguments

[pmags]

Is there a recommended approach or workaround to get `parseopt.getopt` to parse 
negative numbers as positional arguments rather than short options?

For example, given the following command line, getopt will treat `-10` as a 
`cmdShortOption` rather than a positional argument.
    
    
    tempconvert -10 F --to=C
    
    
    Run
