You need to first download the free distribution of Anaconda3. I highly suggest if you are starting python - start with Python 3 (3.4 right now) and make sure you use the python 3 distribution of Anaconda.
From there, if you are not going to pay for or take any courses, I suggest a few books - and read in this order (I am saving you a few months/years that I wasted), 1.) Introducing Python by Bill Lubanovic, this will serve as a good and quick foundation in the language and some of the real-world applications of it. 2.) (This one will look daunting at first but make sure to read it cover to cover if you have never programmed C/C++ before, because this book will explain most of the idiosyncrasies of the language)Learning Python by Mark Lutz - it is Verbose and I am reading it for my 3rd time (not cover to cover anymore, but I will consume a few chapters to refresh my mental syntax understanding).
After you have read these two books and actually have a solid grip of your understanding of: list comprehensions, generators, decorators - then learn Haskell (not to actually use Haskell daily, but to understand base functional programming). Then move back to python and use functools and you will have a broader understanding of why Python is an awesome language(OOP, Procedural and Functional) and appreciate many of the semantics of the language that newcomers don’t understand without learning other languages.
The data analysis (Python For Data Analysis is the best book I have read on the subject) is built in “batteries included” in Python. So you really need to learn the language to truly tap into the data aspect fully.
Welcome to my Blog , In this article, you are going to learn the top 10 python tips and tricks.

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Table of Contents hide
The Size and declared value and its sequence of the object can able to be modified called mutable objects.
Mutable Data Types are list, dict, set, byte array
The Size and declared value and its sequence of the object can able to be modified.
Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.
id() and type() is used to know the Identity and data type of the object
a**=str(“Hello python world”)****#str**
Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.
Python supports 3 types of numeric data.
int (signed integers like 20, 2, 225, etc.)
float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)
complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)
A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).
The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.
# String Handling
#single (') Quoted String
# Double (") Quoted String
# triple (‘’') (“”") Quoted String
In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.
The operator “+” is used to concatenate strings and “*” is used to repeat the string.

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.
When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

Pandas is one of the predominant data analysis tools which is highly appreciated among data scientists. It provides numerous flexible and versatile functions to perform efficient data analysis.
In this article, we will go over 3 pandas tricks that I think will make you a more happy pandas user. It is better to explain these tricks with some examples. Thus, we start by creating a data frame to wok on.
The data frame contains daily sales quantities of 3 different stores. We first create a period of 10 days using the
date_range function of pandas.
import numpy as np import pandas as pd days = pd.date_range("2020-01-01", periods=10, freq="D")
The days variable will be used as a column. We also need a sales quantity column which can be generated by the
randint function of numpy. Then, we create a data frame with 3 columns for each store.
