Functions in Python

A function is a block of statements in which instruction is given to perform a particular task. It provides code reusability. They provide better modularity of the program. Python has a number of built-in functions and we can have a user-defined function also in it. Functions in Python, we have three parts:

1) Function Declaration

2) Definition

3) Calling

Functions in Python

A function declaration is done first before giving the code to be performed. There is some rule for function definition

1) There is a keyword def followed by the function name and ()

2) The argument and parameter are given in ()

3) Colon: will be used for indentation

4) The first statement of the function is an optional statement in which the documentation string or the docstring

5) The return statement exit the function and the return without argument will be similar to return none

Function definition in Python Programming will be code which we have to run to get the required output. Function calls can be done in two ways

1) Call by value

2) Call by reference

TYPES OF FUNCTION with Few Functions Example:

1) Function with no argument and no return value

2) Function with no argument and with return value

3) Function with argument and no return value

4) Function with argument and with return value

Function Argument:

1) Keyworded

2) Default

3) Variable-length argument

4) Required Argument

The Anonymous Functions:

These functions are called anonymous because they are not declared in the standard manner by using the def keyword. You can use the lambda keyword to create small anonymous functions. For more details visit Python Training Institutes in Pune.

Lambda forms can take any number of arguments but return just one value in the form of an expression. They cannot contain commands or multiple expressions.

An anonymous function cannot be a direct call to print because lambda requires an expression. Lambda functions have their own local namespace and cannot access variables other than those in their parameter list and those in the global namespace.

Although it appears that lambdas are a one-line version of a function, they are not equivalent to inline statements in C or C++, whose purpose is bypassing function stack allocation during invocation for performance reasons.

Built-In Function in Python:

1) Print()-to print any value or anything on the screen

2) Abs()-Return the absolute value of a numeric value

3) Round()-Return the rounded value of a numeric value

4) Max()-return the largest item

5) Sorted()-it will sort in ascending order

6) Len()-give the number of elements in the list or number of characters of the string

7) Type()-give the type of variable

8) Zip()-create the tuples of variable

9) Chr()-return the string representing the character whose Unicode point is the integer given in ()

10) Filter()-Give an iterator for the element of inerrable for which the function give true

ETL Testing vs. Selenium Testing

 Selenium IDE — Selenium IDE is a complete integrated development environment (IDE) for Selenium tests. It allows recording, editing, and debugging tests.

WebDriver — WebDriver is very successful than selenium remote control. Selenium Web Driver accepts commands and sends them to a browser.

API — As an alternative to writing tests in Selenium, tests can also be written in various programming languages. These tests then communicate with Selenium by calling methods in the Selenium Client API. Selenium now provides APIs for Java, C#, Ruby, JavaScript and Python.

Announcement:

There are a lot of frameworks in selenium to work easier Like testing, Maven, cucumber, Jenkins, Robot etc. Basically, frameworks provide solutions and functionalities to a particular problem.

ETL Testing — Basically ETL term refers to Extract data then transform data then load data. You can load or you can set no. of data in a very short time period. ETL Testing is database testing by which you can test data that you are collecting from different clients by using Different Tools.

Informatica tool is using in ETL these days because Informtica is very good in result comparison to other tools. Informatica Workflow Monitor helps in easy, simple and quick job monitoring and recovery. There are many components many content Technogeeks is providing in ETL testing with live projects like Introduction to ETL and DW Concepts, DATA WAREHOUSING LIFE CYCLE, SCD (Slowly Changing Dimensions), ETL Tool Implementation and Testing Concepts, Basic Concepts In SQL, Coding and testing process in different transformation rules, Testing Techniques in ETL, Informatica PowerCenter, Interview preparation, Interview questions and much more help to candidates.

AWS Cloud Computing With Linux Demand in IT Companies

Cloud computing is one of the hot skills in IT Companies and a majority of the projects are based on Amazon web services cloud applications. Cloud-based technologies are the changing era in IT Industry and most of the clients are opting for this Technology in Infrastructure because it is cheaper and lots of processes like security, backup and much more are already taken care of by Cloud vendors. Now clients don’t need to purchase and create their data centres because one can purchase it ready to use on the cloud and can pay rent basis of the volume and processing power used by the organization. The Cloud computing key is Linux and it plays an important role in cloud management and access.

So especially for those who are working as Linux Admin in IT Industry, Cloud Computing Course in Pune is one of the best options for upcoming future technology because now everything moving on the cloud. Now even clients are moving Big Data Hadoop Technology also on the cloud. Another good option is the programming languages era where the best languages in the world are and Python. These two languages have the maximum share of the IT Language-based industry.

Java and Python both are powerful languages and capable to perform lots of magical tasks which are not possible/ too lengthy implementation in other tools. Linux is the most secure operating system and on the other hand, you can look forward to Linux Training in Pune. No doubt that language can’t be removed from the computer world because whenever there is any customization or development for a scratch like a requirement then always the only possible solution is programming for code customization and upgradation.

There are many classes, institutes available in Pune Maharashtra for Python, Data Science, Java, AWS. One of the best institutes I found is Technogeeks, Aundh. They provide the best training with complete hands-on skill sets and tools and I personally suggest that one can join at least free Demo Session they provide on all technology and see their professionalism why I am recommending is because I was able to manage and get the job after doing the Training from Technogeeks on AWS and Linux.

My Sister has done Java and Python from Java Training in Pune course from there and overall it is a good institute for AWS and Python both. There are many jobs available in the IT industry based on skill sets mention above and one can crack an interview only if he/she also put effort along with help and get the real time scenarios also to get detailed knowledge.
