Q10:Consider the function fun, which is defined below:

def fun (x):

x [0] = 5

return x

There is a list with three numbers.

g = [10,11,12]

Which of the following will be the output of this print statement:

print fun (g), g

1- [5, 11, 12] [5, 11, 12]

2- [5, 11, 12] [10, 11, 12]

3- [10, 11, 12] [10, 11, 12]

4- [10, 11, 12] [5, 11, 12]

Q11:Suppose you are given a df data frame.

df = pd.DataFrame ({'Click_Id': ['A', 'B', 'C', 'D', 'E'], 'Count': [100,200,300,400,250]})

Now you want to change the column name "Count " in df to " Click_Count ". So, you wrote the following code to accomplish this step.

df.rename (columns = {'Count': 'Click_Count'})

What will be the result of the printout below?

print df.columns

1- ['Click_Id', 'Click_Count']

2- ['Click_Id', 'Count']

3- Print Error

4- None of the above

Q12:Let's say you are given 2 lists - City_A and City_B.

City_A = ['1', '2', '3', '4']

City_B = ['2', '3', '4', '5']

Both cities have the same values. Which of the following codes will find the names of all cities that are present in "City_A" but not in "City_B".

1- [i for i in City_A if i not in City_B]

2- [i for i in City_B if i not in City_A]

3- [i for i in City_A if i in City_B]

4- None of the above
