[New-bugs-announce] [issue47002] argparse - "expected one argument" when used -: in argument

[Pythass]

New submission from Pythass <crazysnob at live.it>:

By using argparse, and by passing a string as argument that has both a dash "-" and colon ":", python returns "expected one argument" error, despite it works when I use only "-" without ":".

An example of code is attached at the ticket.

Examples of triggering "expected one argument" error:
python test.py -u -1:00
python test.py -u -1:

Examples of NON triggering "expected one argument" error:
python test.py -u -1
python test.py -u=-1:00
