argparse

问题 I really dont think what I'm asking for is difficult but I can't find anything that helps without it talking about integers or different kind of arguments. I just want to call different functions using argparse. I want to call either the SHC updater, HCM, or Cloud. Right now it does all 3. I need

问题 Python's argparse lets me define argument names containing a dot in the name. But how can I access these ? import argparse parser = argparse.ArgumentParser() parser.add_argument("inputfile.txt") parser.add_argument("outputfile.txt") args = parser.parse_args(['hello', 'world']) # now args is: #

问题 I am trying to pass multiple file path arguments via command line to an Rscript which can then be processed using an arguments parser. Ultimately I would want something like this Rscript test.R --inputfiles fileA.txt fileB.txt fileC.txt --printvar yes --size 10 --anotheroption helloworld -- etc..

问题 I have a function that takes as parameters an input folder (required) and output folder (optional), but I want the default value of the (optional) output folder to be the input folder. I can do this of course using, e.g. p = argparse.ArgumentParser(description="blah") p.add_argument('inpath',

问题 I want to write a simple tool that takes an arbitrary number of input files and performs one operation on each of them. The syntax is stupidly simple: mytool operation input1 input2 ... inputN Some of these operations may require an extra argument mytool operation op_argument input1 input2 ...

问题 I want to generate custom error messages for particular usage errors in my command-line program that uses the argparse library. I know I can override the general presentation of the error by subclassing argparse.ArgumentParser : class HelpParser(argparse.ArgumentParser): def error(self, message):

问题 Is it possible to use argparse to capture an arbitrary set of optional arguments? For example both the following should be accepted as inputs: python script.py required_arg1 --var1 value1 --var2 value2 --var3 value3 python script.py required_arg1 --varA valueA --var2 value2 --varB valueB a priori

问题 How do I check if the flag --load is present? #!/usr/bin/env python3 import argparse import os parser = argparse.ArgumentParser(description='Process some integers.') parser.add_argument('-l', '--load', nargs='?', metavar='path', help='Load all JSON files recursively in path') args = parser.parse
