How to use Python Interactive Shell in an easy way

Image
By
Python Interactive Shell
[Python Interactive Shell]

It's like this: Python leads a double life. It's an interpreter for scripts that you can run from the command line or run like applications, by double-clicking the scripts. 

What is Interactive Shell

But it's also an interactive shell that can evaluate arbitrary statements and expressions. This is extremely useful for debugging, quick hacking, and testing.

I even know some people who use the Python interactive shell in lieu of a calculator! 

Launch the Python interactive shell in whatever way works on your platform, and let's dive in with the steps shown here:

First Steps in the Interactive Shell
>>> 1 + 1 ❶
2
>>> print 'hello world' ❷
hello world
>>> x = 1 ❸
>>> y = 2
>>> x + y
3
❶ The Python interactive shell can evaluate arbitrary Python expressions, including any basic arithmetic expression.
❷ The interactive shell can execute arbitrary Python statements, including the print statement. 
❸ You can also assign values to variables, and the values will be remembered as long as the shell is
open (but not any longer than that).

Python Syntax Rules Eliminate Errors Before you start debugging

By
In Python, if you know syntax rules, you can eliminate errors. The basic mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Python is case sensitive. So using the wrong identifier gives an error.
Indentation is unique to Python. You cannot find this kind of rule in any other programming languages Python Syntax Cheat Sheet These are the main areas you need to focus while writing a Python program. You need to learn rules. Else you need to waste a lot of time fixing the issues or errors.
Indentation or Syntax ErrorsExceptionsHandling Exceptions
1. Indentation If you do not follow proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that.

In if loop, the if, elif, and else should have same indentation. Not only, the statement inside of them should have same indentation.Understand these examples a good material on indentation for you.   2. Exceptions  Python raises exception, wh…

Python Improved Logic Easy Way to Calculate Factorial

By
I am practicing Python programming. This post is you can write logic to calculate factorial in function. This function you can call it a user-defined function. The function name is 'factorial.py'. In real-time, you can write a program in a file and run it in python console. The main task of a developer is to create functions for the reusable code. They call these functions whenever they need. Factorial calculation program for supplied input value. Factorial Logic in Python I have completed this logic in 3 steps. Write factorial.pyImportExecute it Write Factorial.py  Here you need to define a function. Use 2 for loops, and write your logic. This is done on LInux operating system. You can also try on Linux.
After, ESC command Use, :wq to come out of the module. Import Factorial.py Go to Python console, using 'python' command. Use import factorial.py command.


Execute Factorial.py  >>> factorial.fact(5) It will show the result of factorial. Bottom line  Factorial o…

Calculate Circle Area the Logic You Need to write in Python

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


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 area of circle using two different methods. First I followed by creating an user defined function. Next directly I ran  the formula in interpreter.


Method-1 Steps I have followed to Calculate Area Using FunctionLogged into Cent Os (Linux) Create .py module Import .py module into Python Execute .py module  1. Log in I have first logged into CentOS. You can see there '$'.

2. Creating .py module To create .py module. You can use vi editor command.

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

Top 10 SCALA Quiz Questions for Programmers

By
Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do.


To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them. There’s a REPL and IDE worksheets for quick feedback.

Developers like it so much that Scala won the ScriptBowl contest at the 2012 JavaOne conference. At the same time, Scala is the preferred workhorse language for many mission critical server systems. The generated code is on a par with Java’s and its precise typing means that many problems are caught at compile-time rather than after deployment.


At the root, the language’s scalability is the result of a careful integration of object-oriented and functional language concepts.(Ref-what is Scala).View Su…
