How to call function with dynamic parameter input

Question

I would like to call a function with dynamic parameter input, I am not sure if it is possible, any suggestion is welcome.

The scenario is like below:

I have a function with 5 parameters like this

function(p1=v1, p2=v2, p3=v3, p4=v4,p5=v5)

v1-v5 are saved in an excel file and can be empty, if the value for a parameter is none(nothing entered in the excel), the parameter should not appear when call the function.

For example, if v2=None, when I call the function, it will look like function(p1=v1, p3=v3, p4=v4,p5=v5).

Is it possible by checking the value of each parameter that I can call the function dynamically with parameters that have meaningful value?

Perhaps you can do it like this;

When you declare your function you can set a default value and handle that case

def myFunction(p1=None, p2=None):
   // do some work and check if values exist

Then call your function like below:

result = myFunction(p1=v1)

Notice how we do not have to enter a value for p2. If no value is declared the default value of None will be set.

As an aside depending on your data/usecase you might also want to consider using a different data structure like an array/list

def myFunction(myList):
    // loop through myList and do something with the data

aList = [v1,v3,v4,v5]
result = myFunction(aList)
