Python Top Libraries You Need to Create ML Model

Creating a Model of Machine Learning in Python, you need two libraries. One is 'NUMPY' and the other one is 'PANDA'.


For this project, we are using Python Libraries to Create a Model.
What Are Key Libraries You Need I have explained in the below steps. You need Two.
NUMPY - It has the capabilities of CalculationsPANDA - It has the capabilities of Data processing. To Build a model of Machine learning you need the right kind of data. So, to use data for your project, the Data should be refined. Else, it will not give accurate results. Data AnalysisData Pre-processing How to Import Libraries in Pythonimportnumpy as np # linear algebra
importpandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)

How to Check NUMPY/Pandas installed After '.' you need to give double underscore on both the sides of version. 
How Many Types of Data You Need You need two types of data. One is data to build a model and the other one is data you need to test the model. Data to build…

Calculate Circle Area the Logic You Need to write in Python

In Python, you can calculate the circle area easily by using the function. The purpose of Python is to use in data analysis.

Calculate circle area in Python using function. The logic you need given for your projects.

You need this logic in many areas. You can use in your present finance projects or new ones.

Benefits of function you can re-use the same code number of times
       
         Area of Circle=pi*r*r       
 

Area of Circle Steps Given - You Can do Using Two Methods, Explained Both Methods

I have given steps to calculate the area of a circle using two different methods. First I followed by creating a user-defined function. Next, directly I ran the formula in the interpreter.


Method-1

Steps I have followed to Calculate Area Using Function

  1. Logged into Cent Os (Linux)
  2. Create .py module
  3. Import .py module into Python
  4. Execute .py module

 1. Log in

I have first logged into CentOS. You can see there '$'.

login centos

2. Creating .py module

To create ".py" module. You can use the vi editor command.

You need 'import decimal' to get Decimal values. Else you will get the only integer.

py module

I have given the PWD command. Which tells the present working directory.

There you can give ls command.

You can see the list of .py modules. Here, you can see two kinds of modules. Those are .py and .pyc.

The .py is our module, which contains a function to calculate the Circle area. The .pyc module is a Python compiled module that will store in the same directory. When you first import the module in Python, the " .Pyc" module will create by Python.

list of modules

3. Importing the Module from Operating system


You need to first go to Python using Python command. There, you can give an import module-name.

During import .py for the module extension not required.

import module

 4. Execute Function with Circle area

You can pass a value to function to get the area of a circle.

result circle area

The value is rounded to 2 digits. I used round() function.

Bottom Line

Steps I used explained to calculate the area using the function.

In a similar way you can calculate areas for:

  1. Rectangle area
  2. Circle perimeter

Method-2

How to calculate Circle area using the command line

You can give values directly in the Circle area formula to get area.

command line circle area

       
>>> import decimal
>>> from decimal import Decimal
>>>> Decimal(22)/Decimal(7)*10*10
