[Python Patterns] Using Argparse
This is just a simple pattern I use when I need a quick and dirty script.
I usually base most of my scripts on this.
Make sure you pip install argparse
before using the script.
This just repeats an IP address back to you.
# argparse_example.py
import argparse
import sys
# Example usage
# python argparse_example.py -i 10.10.10.1
# Example output
# You entered this data: {'ip_addr': ['10.10.10.1']}
def main(**kwargs):
""" argparse example """
# String Formatting
print(kwargs['ip_addr'])
data = 'You entered this data: {}'.format(kwargs)
return print(data)
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument('-i', nargs='+', dest='ip_addr',
help='Enter the ip address', required=False)
args = parser.parse_args()
# Convert the argparse.Namespace to a dictionary: vars(args)
arg_dict = vars(args)
# pass dictionary to main
main(**arg_dict)
sys.exit(0)
My blog posts tagged with "Python Patterns" are designed to be a quick look reference for some Python code snippets I use a lot. They are written to be a quick starting point for future projects so I do not need to type as much.
