问题 I was looking at someone else's code and following python code; import argparse ap = argparse.ArgumentParser() ap.add_argument("-i", "--image", required=True, help="path to the input image") args = vars(ap.parse_args()) gives the following error on the last line; usage: sample.py [-h] -i IMAGE sample.py: error: the following arguments are required: -i/--image How can I fix this problem? Nothing I have tried so far seems to help. 回答1: When running sample.py , you need to specify the -i / -

问题 So I'm trying to teach myself how to use the python library argparse via the tutorial here. The example is given by the following piece of code which is saved as tut.py . import argparse parser = argparse.ArgumentParser(description='Process some integers.') parser.add_argument('integers', metavar='N', type=int, nargs='+', help='an integer for the accumulator') parser.add_argument('--sum', dest='accumulate', action='store_const', const=sum, default=max, help='sum the integers (default: find

Can I check if a value was supplied by the default or by the user?

由 坚强是说给别人听的谎言 提交于 2021-01-03 03:42:14
问题 Is there a way, when using argparse , to tell whether a field has a value because the user specified it or because it was not specified and got the default value? Note: I would also like to consider the case where the user explicitly specifies the default value. I would like to use argparse to process command line arguments, and I would like to use formatter_class=argparse.ArgumentDefaultsHelpFormatter to display what the default value will be for fields that are not specified. In addition, I

argparse with multiple optional flags in one dash

问题 Is it possible to associate multiple flags with a single dash in argparse as in this standard Linux argument style? tar -xvf some_filename.tar 回答1: This will do the trick. Most likely, you didn't include the short form for each argument. import argparse parser = argparse.ArgumentParser(description='... saves many files together...') parser.add_argument('--extract', '-x', action='store_true', help='extract files from an archive') parser.add_argument('--verbose', '-v', action='store_true', help
