Python is a powerful programming language that can be used to automate many tasks. One such task is calling a parameter varying function. This can be done using the Python library, argparse.
Argparse is a Python library that makes it easy to write user-friendly command-line interfaces. It can be used to parse the arguments of a function and call the function with the parsed arguments.
To use argparse, we first need to import it:
import argparse
We can then create an ArgumentParser object:
parser = argparse.ArgumentParser()
We can then add arguments to the parser:
parser.add_argument(“x”, type=int, help=”The value of x”)
parser.add_argument(“y”, type=int, help=”The value of y”)
We can then parse the arguments:
args = parser.parse_args()
We can then call the function with the parsed arguments:
print(add(args.x, args.y))
The add function is a parameter varying function that takes two arguments, x and y, and returns the sum of them.
We can also add a default value for an argument:
parser.add_argument(“x”, type=int, default=0, help=”The value of x”)
If we don’t specify a value for x, it will default to 0.
We can also make an argument optional by specifying the required=False keyword argument:
parser.add_argument(“y”, type=int, required=False, help=”The value of y”)
If we don’t specify a value for y, it will default to None.
We can also specify that an argument can take multiple values:
parser.add_argument(“z”, type=int, nargs=”+”, help=”The value of z”)
If we don’t specify a value for z, it will default to an empty list.
Argparse is a powerful tool that can be used to write user-friendly command-line interfaces. It can be used to parse the arguments of a function and call the function with the parsed arguments.
