Python argparse. The argparse module makes it easy to write user-friendly command-line interfaces. It parses the defined arguments from the sys.argv.. The argparse module also automatically generates help and usage messages, and issues errors when users give the program invalid arguments.

After you’ve imported it you have to create a parser or an ArgumentParser object that will store all the necessary information that has to be passed from the python command-line. import argparse # パーサーを作る parser = argparse.ArgumentParser (prog='argparseTest.py', # プログラム名 usage='Demonstration of argparser', # プログラムの利用方法 description='description', # 引数のヘルプの前に表示 epilog='end', # 引数のヘルプの後で表示 add_help=True, # -h/–help オプションの追加) # 引数を解析する args = parser.parse_args () import sys import argparse import getpass def main(args): if args['username'] is None: print 'No user name specified. Login to WebCTRL needs a user name and password. Check all options for this command via -h' sys.exit(1) else: username = args['username'] if args['password'] is None: password = getpass.getpass('No password specified via -p. import argparse parser = argparse.ArgumentParser(description='Change the option prefix characters', prefix_chars='-+/',) parser.add_argument('-a', action="store_false", default=None, help='Turn A off',) parser.add_argument('+a', action="store_true", default=None, help='Turn A on',) parser.add_argument('//noarg', '++noarg', action="store_true", default=False) print parser.parse_args() import argparse parser = argparse.ArgumentParser(description='This is default value of desc') Here we have imported the argparse module using the import statement.

To start using the argparse module, we first have to import it. import argparse parser = argparse.ArgumentParser() parser.parse_args() Run the code. Run the code with the –help option (Running the script without any options results in nothing displayed to stdout) import sys import argparse import getpass def main(args): if args['username'] is None: print 'No user name specified.

First, you import the argparse module to make it available for use in your program. Next, you create a dictionary data structure tank_to_fish that maps tank names (like tank_a and tank_b) to string descriptions of fish held in those tanks.. You instantiate an instance of the ArgumentParser class and bind it to the parser variable. conda install linux-64 v1.4.0; win-32 v1.4.0; win-64 v1.4.0; osx-64 v1.4.0; To install this package with conda run one of the following: conda install -c conda-forge argparse 2020-02-07 2018-08-13 2020-02-22 argparse¶ argparse is a module for handling command line arguments. Examples of what a module does: create arguments and options with which script can be called; specify argument types, default values; indicate which actions correspond to arguments; call functions when argument is specified 2019-12-18 argparse_utils.

The program defines what arguments it requires, and argparse will figure out how to parse those out of sys.argv.
