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):
print( ' The product of the numbers is \t:

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

Now, you are good to write functions and exceptions.
