Question
Match each python statement with the best description of its purpose. Assume a minimal program like: import argparse parser = argparse . ArgumentParser(description="A Python program') parser.add argument('value') parser.add argument(-f args = parser.parse..args() print (args.value) A. Access an argument value Specify a positional argument Parse arguments given on the command line import argparse Python program') parser.add argument ('value') parser.add argument (-f) args = parser.parse args() D. Create an argument parser object E Make the argparse module available to use in a Python program Specify an optional argumentExplanation / Answer
1) import argparse - (E) -> It makes the argparse module available to be used in the program.
Explanation:- import statement in python allows to use other modules to be available in the program. That way it encouages reusability and modularity. So that programmers dont need to write everything from scratch.
2) parser = argparse.ArgumentParser(description='A Python Program') -> (D) -> creates an argument parser object
Explanation:- As the method ArgumentParser returns something which is captured in parser. It is evident that it creates an argument parser object
3) parser.add_argument('value') -> (B) -> Specify a positional argument
Explanation:- From the statement it is clear that argument is specified and is not an optional one
4) parser.add_argument('-f') -> (F) -> Specify an optional argument
Explanation:- From the statement it is clear that argument is specified and is an optional argument
5) args = parser.parse_args() -> (C) -> Parse arguments given on the command line
Explanation:- As per the module and method it indicates the arguments are parsed which are given on the command line. It does not look like accessing an argument value because parse_args indicates some thing getting parsed.
