(Python Example for Beginners)
Write a Pandas program to display a summary of the basic information about a specified DataFrame and its data.
Sample DataFrame:
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’]
Sample Solution :
Python Code :
Sample Output:
Summary of the basic information about this DataFrame and its data: <class 'pandas.core.frame.DataFrame'> Index: 10 entries, a to j Data columns (total 4 columns): attempts 10 non-null int64 name 10 non-null object qualify 10 non-null object score 8 non-null float64 dtypes: float64(1), int64(1), object(2) memory usage: 400.0+ bytes None

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
