Question

Practice: Look at the following function header:

def foo(a, b, c, d, e)

answer the following questions:

1. How many parameters this function has
2. What is the name of this function
3. If we call the function like this foo( 3, 2, 1, ‘c’, “Wdu”) what values will be assigned to a, b, c, d, e ?
4. If we call function like this foo( 3, 2, 1, ‘c’, “Wdu”) what will be data types of a, b , c, d, and e.

Answer 1

Below is the answer of all of your questions :

a.) Five parameters (a,b,c,d,e)

Explanation : Syntax of python function is def nameoffunction( single or multiple parameter seperated by ,):

So in your function def foo(a, b, c, d, e) , a b c d and e are five parameters.

b.) foo

Explanation : Syntax of python function is def nameoffunction( single or multiple parameter seperated by ,):

So in your function def foo(a, b, c, d, e) , foo is the name of this function .

c.) a = 3 , b = 2, c = 3 , d = c , e = Wdu

Explanation : Values are assign according to order of parameter. So 3 is assign to a , 2 is assign to b , 1 is assign to c, c is assign to d and Wdu is assign to e. Below is the screenshot of values assignment :

e.) a = int , b = int , c = int , d = str , e = str

Explanation : 3 2 and 1 are int. c and Wdu are str. Single and double have no difference in python and both are considered as string. Below is the screenshot of data types assign to variable.

You can check your answers of c and d by using following code :

def foo(a, b, c, d, e):
   print ("a =", a, type(a))
   print ("b =", b, type(b))
   print ("c =", c, type(c))
   print ("d =", d, type(d))
   print ("e =", e, type(e))
   return;

# Now you can call sum function
foo( 3, 2, 1, 'c', "wdu");
