Basics of Calculations_Calculator_Built in Function Assignments

Integer Division %/%

Integer Division :  Division in which the fractional part (remainder) is discarded

> c (2, 3, 5, 7)  % / %  c(2,3)

[1]  1  1  2  2

Modulo Division (x mod y)  %%:

x mod y : modulo operation finds the remainder after division of one number by another

> c (2,3,5,7)  %% 2
  [1]  0  1  1  1

Maximum: max

Maximum: min

Overview Over Further Functions

Example :

> abs ( -4)
  [1] 4

> abs (c(-1, -2, -3, 4, 5) )
 [1]  1  2  3  4  5

> sqrt (4)
  [1]  2

> sqrt ( c(4,9,16,25) )
  [1]  2  3  4  5

 
 > sum (c(2,3,5,7) )
  [1]  17

> prod ( c( 2,3,5,7) )
  [1]   20

> round  (1.23)
  [1]  1

> round (1.83)
  [1]  2



Assignments

Assignments can be made in two ways:

>  x<-6
>  x
    [1]   6

> mode(x)
  [1]  "numeric"

> x=8
> x
   [1]   8

>  mode (x)
    [1]  "numeric"


An assignments can also be used to save values in variables:

>  x1  <-  c(1,2,3,4)

>  x2  <-  x1^2

>  x2
  [1]  1  4  9  16

ATTENTION: R is case sensitive (X is not the same as x

Java vs Python Comparison

Java :-

It is a fast, secure and reliable general purpose computer programming language.

Python :-

A Readable, efficient and powerful high level programming language.

1. Speed

Java 
    → Statically Typed and Faster than Python
Python
    → Dynamically typed and Slower than Java.

2. Legacy :-

Java 
    → Java legacy systems are typically larger and numerous
Python
    → Python has less legacy problem

3. Code

Java
    → Longer lines of code when compared to Python
Python
    → Shorter Lines of code when compared to Java

4. Databases

Java
     → Most popular and widely used database
Python
      → Access layers are weaker than Java's JDBC

5. Practical Agility

Java
       → Popular for mobile and web applications
Python
        →  Popular for Data Science, ML, AI and IoT.

6. Trends

7. Salary 

8. Syntax 

Basic Differences

Java
     → Java is a compiled language.
     → Java is an object oriented programming language.
     → Java is statically typed.
Python
     → Python is an interpreted language.
     → Python is a scripting language.
     → Python is dynamically typed.

Number of  Lines

Java
        public class HelloWorld {
             public static void (string[] args)  {
                   // print "Hello World" to the terminal window.
                   System.out.println("Hello, World");
              }
       }
Python
             The program prints Hello, World!
          print ("Hello, World!");

 Semicolon

Java
              class Programming  {
                    // constructor method
                Programming ( )  {
                  System.out.println ("constructor method called");
                       }
                public static void main(string[ ] args)  {
                  Programming object = new programming ( );
                  }
             }
Python
                class Student:
                   # Constructor - Parametrized
                   def _int_(self, name):
                    print ("This is parametrized constructor")
                       self.name = name
                    def show (self)
                      print ("Hello", self.name)
                student = Student ("Irawen")
                   student.show( )

Top 10 Python Libraries

1. Pandas

Pandas is a software library written for the python programming language for data manipulation and analysis.

Pandas is well suited for many different kinds of data:

• Tabular data with heterogeneously-types columns.
• Ordered and unordered time series data.
• Arbitrary matrix data with row and column labels.
• Any other form of observational / statistical data sets.

 The data actually need not be labeled at all to be placed into a pandas data structure.

2. NumPy

Numpy is the core library for scientific computing in Python. It provides a high-performance multidimensional array object, and tools for working with these arrays.

3. Matplotlib

Matplotlib is a Python package used for 2D graphics.

• Bar graph
• Histograms
• Scatter Plot
• Pie Plot
• Hexagonal Bin Plot
• Area Plot

4. Selenium

The selenium package is used to automate web browser interaction from Python.

5. OpenCV

OpenCV- Python is a library of Python designed to solve computer vision problems.

6. SciPy

Scipy is a free and open-source Python library used for scientific computing and technical computing.

7. Scikit-Learn

Scikit-learn (formerly scikits.learn) is a free software machine learning library for the Python programming language. It features various classification, regression and clustering algorithms.

8.  PySpark

The Spark Python API (PySpark) exposes the Spark programming model to Python.

9. Django

Diango is a Python web framework. A framework provides a structure and common methods to make the life of a web application developer much easier for building flexible, scalable and maintainable web applications
