The header of a Python function is shown below:

def result(one, two, three = 3, four)

(a) How do we call the situation with the third parameter in this header?

(b) Indicate the method of correspondence between formal and actual parameters

that is used in the following function call:

result(four = 14, two = 22, one = 1, three = 33)

(c) Explain what is wrong with the following function call:

result(14, four = 44, 2, 3)

Expert Solution

Dear Student ,

As per requirement submitted above kindly find below solution.

Question a:def result(one, two, three = 3, four)

In python to a function first need to pass the default arguments and then last argument need to be passed as non default argument
Here in the given function result three=3 needs be last argument like def result(one, two,four,three = 3)

********************************

Question b:result(four = 14, two = 22, one = 1, three = 33)

Here actual parameters are passed in the function call
and formal parameters that are passed in function definition
In the given function call with parameter name each parameter actual to formal match as it is , this means
- four=14
- two=22
- one=1
- three=33
- same is mapped with formal parameters.

************************************

Question c:result(14, four = 44, 2, 3)

In the given function call instead of four=44 need to be written as three=44
and this argument need to be passed as last argument
like result(14, 2, 3,three = 44)
