Best Machine Learning Book for Beginners

You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.

Python 'getsizeof' Return Value a Quick Example

In Python, we use objects like List (arrays). You already know that Objects have some data. Counting the number of elements present in it is not easy. You may ask a question on how to get the size.

Do not worry, I am sharing the command for you.

How to Import the Library?

>>> import sys

Sys library is the library you need to import to use the SIZE commands.

Congrats for you since you have now imported the SYS library. The command name is getsizeof.


Check the below example.

print("An Integer:")

 i = int(100) 

print(sys.getsizeof(i))


The result will be: 100

If I want to say more about the size command, it is length like command. It gives the result based on the object. Suppose, if you use Strings, you will get String length.

Python Command to get the Size of an Object


Best Example of SIZE command.

Example:1

print("Empty string:") 

empty_string = "" 

print(sys.getsizeof(empty_string)) 


Example:2

print("A normal string") 

s = "Hello world" 

print(sys.getsizeof(s))


Example:3

 print("Increasing string:") 

for i in range(0,5): 

     empty_string = empty_string + chr(i) 

     print(sys.getsizeof(empty_string))

I am practicing Hyperledger. This is one of the top listed blockchains. This architecture follows R3 Corda specifications. Sharing the interview questions with you that I have prepared for my interview.

Though Ethereum leads in the real-time applications. The latest Hyperledger version is now ready for production applications. It has now become stable for production applications.
The Hyperledger now backed by IBM. But, it is still an open source. These interview questions help you to read quickly. The below set of interview questions help you like a tutorial on Hyperledger fabric. Hyperledger Fabric Interview Questions1). What are Nodes?
In Hyperledger the communication entities are called Nodes.

2). What are the three different types of Nodes?
- Client Node
- Peer Node
- Order Node
The Client node initiates transactions. The peer node commits the transaction. The order node guarantees the delivery.

3). What is Channel?
A channel in Hyperledger is the subnet of the main blockchain. You c…

Python Assigning Multiple Values at Once

Image
Assigning values to a variable is similar to other languages. In python, you can find different styles. Usually, a variable takes or stores values when the programmer assigns. Check my below example for understanding quickly. Here is Python For Loop Tricky Example.***Python Assigning the Values At once.a = 1b = 1c = 1d = 1or, you can assign simultaneously as;a=b=c=d=1
Python Assigning Multiple Values at Once The other way you can assign as;a, b, c, d = 10, 1, 3.5, 'Srini'From the above, you can understand as below:The '10' assigns to a.The '1' assigns to b.The '3.5' assigns to c.Then 'Srini' to d. ReferencesPython Basics Variable Assignment
