How do i create custom tags for taking the input string in command line and store them in a variable in Python
The format for taking the input is:
myprogram.py -f "string1" -t "string2" -i "string 3 some directory path" 
you should use the argparse Python module to parse the CLI parameters. I have written an example for you.
Official documentation of argparse: https://docs.python.org/3/library/argparse.html
Code:
from argparse import ArgumentParser parser = ArgumentParser(description=__doc__) parser.add_argument( "-f", dest="first_string", help="Your first string parameter", required=True, ) parser.add_argument( "-t", dest="second_string", help="Your second string parameter", required=True, ) parser.add_argument( "-i", dest="third_string", help="Your third string parameter", required=True, ) input_parameters, unknown_input_parameters = parser.parse_known_args() # Set CLI argument variables. first_arg = input_parameters.first_string second_arg = input_parameters.second_string third_arg = input_parameters.third_string print("-f: {}\n" "-t: {}\n" "-i: {}".format(first_arg, second_arg, third_arg)) Some output:
>>> python3 test.py -f "string1" -t "string2" -i "string 3 some directory path" -f: string1 -t: string2 -i: string 3 some directory path >>> python3 test.py -t "string1" -f "string2" -i "string 3 some directory path" -f: string2 -t: string1 -i: string 3 some directory path >>> python3 test.py -t "string1" -f "string2" -i "string 3 some directory path" -x "Unused" -f: string2 -t: string1 -i: string 3 some directory path >>> python3 test.py -t "string1" -i "string 3 some directory path" usage: test.py [-h] -f FIRST_STRING -t SECOND_STRING -i THIRD_STRING test.py: error: the following arguments are required: -f >>> python3 test.py -h usage: test.py [-h] -f FIRST_STRING -t SECOND_STRING -i THIRD_STRING optional arguments: -h, --help show this help message and exit -f FIRST_STRING Your first string parameter -t SECOND_STRING Your second string parameter -i THIRD_STRING Your third string parameter
