Question

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]

 

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.

 

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)

                                       iv.    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.
