Hi Guys. I have a question here. Basically what I understood was that argparse module is used to get input from user when running a python file from cmd/powershell. This can be done using input() function as well. So why exactly we will use argparse. Harry Bhai or Anyone, Please clarify?

[@johnme60]

Imagine a plastic box , this box has different sections , the box is totally closed. Now you have pour down liquid in every section of this box. Input function : - this is like putting pipes in each section permanently and leave them opened for liquid pouring. agrs : - The box is closed , but you can shove down a pipe , pour liquid and pull out the pipe in any section. [ Args behave like a optional argument utility , you can have different functionality depends on the given input, the program won't ask you for any input , it's your choice what do you want to give as input from the wide variety of options]
