How to skip the parameters of a function in python?

Question

I am trying to skip parameters while calling a function. Could you please help me how to do this?

Example:

I have to call below function which is having 3 parameters:

send_mail(audit_df, LOG_FILE, Duration)

I have to call above function to skip 1st and 3rd parameters. How can i do this?

Are you writing that function, or is that function provided by someone else? — user202729, Aug 18 '20 at 05:40
And the other two have sensible defaults? What would you like those variables to be when you don't explicitly set a value? — tdelaney, Aug 18 '20 at 05:43
Change it like this: ```send_mail( LOG_FILE,audit_df=DEFAULT_VALUE, Duration=DEFAULT_VALUE)``` and ignore them with DEFAULT_VALUE — Mehdi Mostafavi, Aug 18 '20 at 05:44
If you are writing that function, use keyword arguments with default values. But that's just _basics_. — musicamante, Aug 18 '20 at 05:45

You can setup default values for the parameters. I don't know what works for you, so I just set them to None.

def send_mail(audit_df=None, log_file=None, duration=None):
    do all the things

when calling

send_mail(log_file="myfile")

For a little light reading see the Function definitions section of the docs.

You can place "None" in place of the parameter.

This is going to make python assume that it is Nothing and will do nothing.

Python will assign `None` to the variables but after that, its up to the code what to do. Its not that its nothing and python will do nothing, its that `None` is assigned and if the code doesn't handle that case, exceptions will ensue. – tdelaney Aug 18 '20 at 05:47
