(Python Example for Beginners)
Write a Pandas program to subtract two timestamps of same time zone or different time zone.
Python Code :
import pandas as pd print("Subtract two timestamps of same time zone:") date1 = pd.Timestamp('2019-03-01 12:00', tz='US/Eastern') date2 = pd.Timestamp('2019-04-01 07:00', tz='US/Eastern') print("Difference: ", (date2-date1)) print("nSubtract two timestamps of different time zone:") date1 = pd.Timestamp('2019-03-01 12:00', tz='US/Eastern') date2 = pd.Timestamp('2019-03-01 07:00', tz='US/Pacific') print("Difference: ", (date1.tz_localize(None) - date2.tz_localize(None)))
Subtract two timestamps of same time zone: Difference: 30 days 18:00:00 Subtract two timestamps of different time zone: Difference: 0 days 05:00:00

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.
