如何在python中跳过一个function的参数？

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?

Answer 1

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.

Answer 2

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

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

Answer 3

This can be done in two ways using

1. **kwargs
2. Optional parameters
