Write a Pandas program to calculate the total of the examination attempts and the mean score in data frame. Display the first four rows in the output.
import pandas as pd
import numpy as np
exam_data = {'name': ['Anastasia', 'Dima', 'Katherine', 'James', 'Emily', 'Michael', 'Matthew', 'Laura', 'Kevin', 'Jonas'],
'score': [12.5, 9, 16.5, np.nan, 9, 20, 14.5, np.nan, 8, 19],
'attempts': [1, 3, 2, 3, 2, 3, 1, 1, 2, 1],
'qualify': ['yes', 'no', 'yes', 'no', 'no', 'yes', 'yes', 'no', 'no', 'yes']}
labels = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j']
df = #TO DO -- Complete the Code
# print(df)
print("\nSum of the examination attempts by the students:")
print() #TO DO -- Complete the Code
print("\nMean score for each different student in data frame:")
print() #TO DO -- Complete the Code
print() #TO DO -- Complete the Code
Expected output
Sum of the examination attempts by the students:
19
Mean score for each different student in data frame:
13.5625
