What is the output of the following code ?

d = {'col1': [1, 4, 3 ], 'col2': [6, 7, 8], 'col3': [9, 0, 1]}
df = pd.DataFrame(d)
print("Original DataFrame")
print(df)
print("New DataFrame :")
dfn = df.drop(df.index[[1, 2]])
print(dfn)

What is the output of the following code ?

data = {'age': [20, 23, 22], 'name': ['Ruhi', 'Ali', 'Sam']} 
df1 = pd.DataFrame(data, index=[1, 2, 3])
print("Before")
print(df1)
df1['Edu'] = ['BA', 'BE' , 'MBA']
print('After')
print(dfl)

Write a program in Python Pandas to create the following DataFrame batsman from a Dictionary :

B_NO	Name	Score1	Score2
1	Sunil Pillai	90	80
2	Gaurav Sharma	65	45
3	Piyush Goel	70	90
4	Karthik Thakur	80	76

Perform the following operations on the DataFrame :

(i) Add both the scores of a batsman and assign to column "Total".

(ii) Display the highest score in both Score1 and Score2 of the DataFrame.

(iii) Display the DataFrame.

Consider the following dataframe, and answer the questions given below:

import pandas as pd
df = pd.DataFrame( { "Quarter1": [2000, 4000, 5000, 4400, 10000],  
"Quarter2": [5800, 2500, 5400, 3000, 2900],  
"Quarter3": [20000, 16000, 7000, 3600, 8200],  
"Quarter4": [1400, 3700, 1700, 2000, 6000]})

(i) Write the code to find mean value from above dataframe df over the index and column axis.

(ii) Use sum() function to find the sum of all the values over the index axis.
