argparse

I'm creating a script that takes both positional and optional arguments with argparse. I have gone through Doug's tutorial and the python Docs but can't find an answer. parser = argparse.ArgumentParser(description='script to run') parser.add_argument('inputFile', nargs='?', type=argparse.FileType('rt'), parser.add_argument('inputString', action='store', nargs='?') parser.add_argument('-option1', metavar='percent', type=float, action='store') parser.add_argument('-option2', metavar='outFile1', type=argparse.FileType('w'), parser.add_argument('-option3', action='store', default='<10', args =

I'm dealing with a (Python 3.x) script (written by someone else) where the input and output are currently specified with flagged optional arguments like so: parser.add_argument('-i', '--input', nargs='?', type = argparse.FileType('r'), default=sys.stdin, dest='inputfile') parser.add_argument('-o', '--output-file', nargs='?', type=argparse.FileType('w'), default=sys.stdout, dest='outputfile') I'd like to upgrade this script so that the input and output file can be specified as positional arguments while maintaining the existing flag arguments for backwards compatibility. I'd also like to

I have written a simple script as an advanced tool for my awk / sed requirements. In the script I compare two files on basis of values from one column of the query file and then extract whole entries from the master file. The script allows you to enter the values for columns and delimiters for each file. The problem is that the 'delimiter' options are not recognized by script when given from command line. Here is my code (partial): ##- - - - - - - -- - - - - - Arguments - - - - - - - - - - - - - -## parser = argparse.ArgumentParser() ## Command line options parser.add_argument("-m", "--master"

I would like to write a Python script that takes some necessary positional and some optional command-line arguments via argparse : Let's call the positional args a , b , c , and the optional arguments x , y , z . In my Python script, I would like to pass these args on to a function; specifically, I want a , b , c to be passed as *args , and x , y , z to be passed as **kwargs , the latter retaining their names. I would like to do this many times with different functions and different numbers of positional and optional arguments. Is there a neat, flexible, and/or pythonic way to do this? Here is

I want this functionality: $ python program.py add Peter 'Peter' was added to the list of names. I can achieve this with --add instead of add like this: import argparse parser = argparse.ArgumentParser() parser.add_argument("--add", help="Add a new name to the list of names", action="store") args = parser.parse_args() if args.add: print "'%s' was added to the list of names." % args.add else: print "Just executing the program baby." Such that: $ python program.py --add Peter 'Peter' was added to the list of names. But when I change --add to add it is no longer optional, how can I still let it

Below are three arguments I am writing in a module. parser.add_argument('--Type',type=str,choices=['a','b','c'],help='Options include: a,b,c.',required=True) parser.add_argument('--Input',default=False,help='Generate input files',required=False) parser.add_argument('--Directory',default=False,help='Secondary directory',required='--Input' in sys.argv) The --Type is possible with three options: a,b,c. Currently, I have it set up so that, if --Directory is true, it requires --Input to be true. However, I would like add an additional condition to --Directory to require --Type to be == 'c'. How do

I a new to Ipython. Currently i have installed Ipython using Anaconda and writing a code to plot chart using jupyter notebook UI. I want to pass few arguments to my working script with the help of argparse module. below is the code.. import argparse parser = argparse.ArgumentParser(description = 'Process display arguments') parser.add_argument('-t', "--test_name", help="Mandatory test name directory path", type=str) parser.add_argument('-s', "--symbolSet", nargs = '?', help="Optional symbolset", const = 'baz', default = 'deafultOne') args = parser.parse_args() if args.test_name is None: print(
