Observe the following program carefully, and identify the error:

def findValue( vall = 1.1, val2, val3):
                 final = (val2 + val3)/ vall
                 print(final)
findvalue()                      #function call

Differentiate between the following with the help of an example:

Argument and Parameter

Consider the following list myList. What will be the elements of myList after the following operation:

myList = [10,20,30,40]

myList.append([50,60])

Consider the following list myList. What will be the elements of myList after the following operation:

myList = [10,20,30,40]

myList.extend([80,90])

What will be the output of the following code segment:

myList = [1,2,3,4,5,6,7,8,9,10]
 for i in range(0,len(myList)):
           if i%2 == 0:
                print(myList[i])

Differentiate between append() and extend() functions of list.

Write a function that returns the largest element of the list passed as a parameter.

Write a function to return the second largest number from a list of numbers.

Write a program to read a list of n integers and find their median.

Note: The median value of a list of values is the middle one when they are arranged in order. If there are two middle values then take their average.

Hint: You can use a built-in function to sort the list.

Write a program to read a list of elements. Input an element from the user that has to be inserted in the list. Also, input the position at which it is to be inserted. Write a user-defined function to insert the element at the desired position in the list.

Read a list of n elements. Pass this list to a function that reverses this list in place without creating a new list.
