Find the error in the following code fragments:

S2 = pd.Series([1, 2, 3, 4, 5], index = range(4))

Find the Error :

data = np.array(['a', 'b', 'c', 'd', 'e', 'f'])  
s = pd.Series(data, index = [100, 101, 102, 103, 104, 105])   
print(s[102, 103, 104] )  

Can you correct the error ?

Consider the following Class12.csv file containing the data as given below:

RollNo	Name	Accounts	Maths	BSt	IP	Eco
10	Ritu Jain	88	67	87	97	56
11	Mridul Mehta	67	78	77	87	90
12	Divij	87	89	78	82	92
13	Yashvi Verma	67	82.3	76.5	98.2	78.6
14	Deepak Virmani	56.7	76.5	88	78	67
15	Jatin Malik	76	66	77	87.5	67.5

(a) Read the csv file into a dataframe df which is stored with tab ('\t') separator.

(b) Write the code to find the total marks (Total_ marks) for each student and add it to the newly-created dataframe.

(c) Also calculate the percentage obtained by each student under a new column “Average” in the dataframe.

Write a program that reads students marks from a ‘Result.csv’ file and displays percentage of each student.
