(Python Example for Beginners)
Write a Pandas program to count of occurrence of a specified substring in a DataFrame column.
Sample Solution:
Python Code :
Sample Output:
Original DataFrame: name_code date_of_birth age 0 c001 12/05/2002 18.5 1 c002 16/02/1999 21.2 2 c022 25/09/1998 22.5 3 c2002 12/02/2022 22.0 4 c2222 15/09/1997 23.0 Count occurrence of 2 in date_of_birth column: name_code date_of_birth age count 0 c001 12/05/2002 18.5 0 1 c002 16/02/1999 21.2 1 2 c022 25/09/1998 22.5 2 3 c2002 12/02/2022 22.0 2 4 c2222 15/09/1997 23.0 4

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.
