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 Function: How to Write Error Logic

Python is one of the top programming languages. Python does support Functions. While writing functions you also need to consider some errors. Those are called exceptions. I am explaining how to give error logic in a function of Python.


Python function error logic

Exception-handling means to have logic for error scenarios. Writing exception I will show in a simple Function.

In this post I will give you syntax for writing function and exception. 

Here is my simple Function that multiplies two numbers.

Logic to write Function in Python to Multiply Two Numbers 

def product (num1,num2):
prod=num1*num2
print( ' The product of the numbers is \t:
'+str(prod)

Parameters used the Python Function
  • The 'def' means you are defining function with a name of 'product'.
  • In the parameters of 'product', you can see TWO variables. Those are to take input from the user for multiplication.
  • prod=num1*num2. That means product of two numbers assigning to 'prod' variable. 
  • Python is dynamic language and you no need to define variables explicitly.
  • Print command displays your result to the terminal or console. 
  • The '\t' tells 'space' between comment and the result.
How Python Function works

How to write error logic in Python Function

In the below code when you supply other than numeric, it sends an error message.

def product(num1,num2):
prod=num1*num2
If num1 or num2 in [ 0,1,2,3,4,5,6,7,8,9]
     print( prints value)
elif
    print( error)

Now, you are good to write functions and exceptions.

Hyperledger Fabric: 20 Real Interview Questions

Image
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…

How to Fix Python Syntax Errors Quickly

Image
In Python, you can call parsing errors Syntax errors. How to fix the syntax errors quickly, I can show in this post. Also, check Python Syntax Errors Cheat Sheet.

What is Python Syntax Error?
If you run the Python code, the interpreter first parses the logic. If any errors found, it is the developer's responsibility to fix them.
Courtesy: Python documentation. >>> whileTrueprint('Hello world') File "<stdin>", line 1whileTrueprint('Hello world')^SyntaxError: invalid syntax
How to Fix the Syntax Error?
First, check for the line number. In the above case, it is '1'. Then look for the symbol '^'. The issue is at the PRINT function. The reason is before the PRINT function you need a colon ':'. That is the reason, you are getting error.
This is a syntax error. Find below the corrected logic: >>> whileTrue :print('Hello world') File "<stdin>", line 1whileTrueprint('Hello world')^Syntax…

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
