(Python Example for Beginners)
Write a Pandas program to convert DataFrame column type from string to datetime.
Original DataFrame (string to datetime):
Sample Solution :
Python Code :
import pandas as pd import numpy as np s = pd.Series(['3/11/2000', '3/12/2000', '3/13/2000']) print("String Date:") print(s) r = pd.to_datetime(pd.Series(s)) df = pd.DataFrame(r) print("Original DataFrame (string to datetime):") print(df)
String Date: 0 3/11/2000 1 3/12/2000 2 3/13/2000 dtype: object Original DataFrame (string to datetime): 0 0 2000-03-11 1 2000-03-12 2 2000-03-13

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.
