[New-bugs-announce] [issue37510] argparse removing more "--" than it should

[Jorge L. Martinez]

New submission from Jorge L. Martinez <jol at fastmail.com>:

$ python -c '
import argparse
p = argparse.ArgumentParser()
p.add_argument("first_arg")
p.add_argument("args", nargs="*")
r = p.parse_args(["foo", "--", "bar", "--", "baz", "--", "zap"])
print(r.first_arg + " " + " ".join(r.args))
'                        

returns:

foo bar baz -- zap

when I think it should return:

foo bar -- baz -- zap
