Consider there is a list i.e.

listA = {20, 10, 5, 15, 3}

Write python code that:

a. Creates a function updateListA(), which takes listA as input parameter, adds 30 after 20, and adds 40 at the end of the listA. [Hint: create a parameterized function]

[01]

b. Creates a function newList(), which takes listA as input parameter and creates a new list newList with same elements as listA but in reverse order. [01]

c. If there is a function defined as below: def example(par1, par2=30):

print(valid)

From the following function calls:

i. example(par1=1) ii. example(1, 2) iii. example(par2=1) iiii. example(par1=5, par2=6) Which call is valid? Write the values of par1 and par2 if a call is valid? Suggest corrections if a call is invalid.
