I'm using argparse
(Python 3.2). A parameter mode
is defined simply as:
p.add_argument('--mode', dest='mode')
I want to call the program from the command line in such a way that parameter mode
is set to an empty string; or at least to a single space ' '
(I can strip whitespace later).
I tried to use (under Windows) program_name --mode ""
and program_name --mode " "
, but neither worked.
This seems to work for me under OS-X:
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--mode')
p = parser.parse_args()
print(p)
and then:
python test.py --mode=
I don't have a windows machine, so I don't know anything about how those operate...
Of course, the other things you mentioned above would work as well on OS-X. The advantage here is that it shouldn't rely on how the shell splits arguments enclosed in quotations which should make it work in more places I would think.
