The argparse module was an addition to Python 2.7 as a replacement for the pre-existing module named optparse. The new module contains the implementation of several functionalities that would have been quite difficult additions to the pre-existing ones, which is the backward-incompatible API changes...
In Python, command-line arguments can be used to add or modify a program’s runtime behavior. Passing the command-line arguments at runtime gives users the flexibility to monitor their program’s runtime behavior and desired outputs. One can do this by using the argparse/ standard input libr...
Python logging system is quite complex, deserving a question in an interview. logger = logging.getLogger(__name__) logger.debug("FYI, here's what you don't see unless you enable me.") To see the message in, let's say, console you have to: Enable logger of the current ...
They are amazing for automating tasks. Plus, they’re super resource-efficient. You know, back in my early days, I once automated a whole bunch of tedious data processing with a simple Python CLI script. It felt like magic, seriously. I saved myself hours of work! Step 1: Setting Up ...

parser = argparse.ArgumentParser(prog='parent') subparsers = parser.add_subparsers() subparsers.add_parser('foo') # how can I associate these subparsers subparsers.add_parser('bar') # with my foo and bar parsers already defined? Does argparse allow this, or do I have to define my su...
Why does my code take so long to run? Python Profilers can answer that question. It tells you which part of the code took how long to run. This lets you focus on that particular part and achieve efficiency. I cover in detail how to use Python profiler, particularly ‘cProfile’, with...
Thanks, I gained more insight into the use of the kargs argument even though I had already used them. The concepts are similar to the ones used in the command line parsing module argparse for giving instant POSIX behaviour to your python 2.7.x scripts: ...
