Program Flow Control Statements

How to Start Coding | Programming for Beginners | Learn Coding | Intellipaat

Like in JavaScript, Python has as similar set of flow control statements, but with slightly different syntax.

If / Else Statement

This is the Python equivalent of the if/else example we saw in the JavaScript section:

x = 10if :    printelse:    print

We defined a variable called x and set its value to 10, followed by our if statement. Since the condition in the parentheses evaluates to True, the code indented after the if statement will be executed, and we will see the string ‘X is GREATER than 5!’ printed to the screen.

In Python, we use the print function for printing information to the screen.

Also note the else statement above, which will print an alternative string to the screen if x if the condition is False.

There are two main differences between the Python code above and the JavaScript code we saw previously. Python uses a colon instead of curly braces to indicate the beginning of the if statement block.

In addition, the indentation of the print function actually matters in Python. In JavaScript, the indentation or white space between statements doesnt matter since JavaScript identifies code blocks using curly braces and identifies the end of a statement using a semi-colon. But in this Python example, there are no semi-colons and no curly braces!

That is because Python actually uses the white space and newline characters to identify the end of statements and code blocks.

While Loops

x = 1while :    print    x = x + 1print

Further Your Knowledge With Java

How long does it take to learn JavaScript? ~ Xenon Tech Tips

Now that weve worked with a couple of higher-level programming languages, lets take it one step lower with Java.

Unlike JavaScript and Python which execute source code in real time using an interpreter, Java is a compiled language. This means a compiler is used to convert Java source code into a form the computer can understand.

Most compilers generate one or more executable files made up of machine code that are ready to run on the specific operating system and hardware platform they were compiled for.

But Java is somewhat special in that it compiles the Java source code into an intermediate form called . This is different than the machine code that most other compiled languages produce. Java bytecode is intended to be executed by something called the Java Virtual Machine .

You can think of the JVM as a program that you install on your computer, which allows you to run Java programs by executing Java bytecode. When people talk about “whether or not Java is installed on a computer,” they are usually asking whether or not the JVM is installed on the computer.

The JVM serves a similar function to the interpreters we discussed in previous chapters. But instead of taking source code as an input, it takes compiled bytecode.

The benefit of this setup is that it allows bytecode compiled on particular operating systems and platforms to be executed by a JVM on any other platform.

Read About Web Frameworks And Mvc

Oftentimes, well find ourselves writing code for very common types of applications. Web applications are applications that rely on the Internet in order to function. Webapps are some of the most commonly created types of software applications.

A web app is essentially a more functional and robust version of a website. Most web apps implement some backend code that resides on a web server and performs logic behind the scenes to support the applications functionality.

Common programming languages to use for a web apps backend code include Python, Java, and JavaScript, among others.

Some functionalities common to most web apps include:

  • Providing a convenient way to dynamically alter content on web pages
  • Performing secure user authentication via a login page
  • Providing robust application security features
  • Reading and writing data to a database

A web framework is a set of code libraries that contain the common functionalities that all web apps use out of the box. Web frameworks provide a system for developers to build their applications without having to worry about writing the code for many of the behind the scenes tasks common to all web apps.

We only need to utilize the parts of the framework that meet the needs of our web app.

For example, if we dont need to connect to a database in a particular web app, we can just ignore the database features and use the other features that we do need.

Bonus: Top Tips For Becoming A Programmer

BEST Way To Learn Programming Language (quickly and easily!) | Placement Series

Congratulations, by now you should understand exactly how to become a computer programmer. I have put together the following bonus tips for people who want to learn programming, but are having trouble getting started.

Whether you are lacking motivation, are having trouble learning the syntax, or simply dont know where to start, the following should help you to understand how to become a programmer:

    • You can never know too much, but you need to start simple. Focus on one language, to begin with, and dont move to the next until you have a good grip of the first. Otherwise, you might get confused.
    • Start taking freelance jobs as soon as you can. Look at Upwork and other freelance platforms, and find jobs that are suited to your skill level. Remember, even having a little bit of programming knowledge means that you have more than most people.
    • Stop worrying about how to be a programmer, and just start learning. Sure, it will be difficult to start with, but things will start to make more sense as you learn. The trick is not to bite off too much to start with.
    • Ask for help. The coding community is super friendly and most people are willing to help fellow programmers learn. Join an online discussion board or chat room, and ask for help when you need it.
    • In the same way, dont be afraid to ask other people to improve your code – in fact, a lot of people will jump at the chance, because it will help them learn too!

Setting Up And Running Code

Taking the first steps after learning the theory

Finally, you are ready to start coding and running some codes!

To set up, you need to download the programming language itself, the links are provided at the end of this article. You will also need to download an IDE which is software to run the code. You can think of the IDE as a nice pretty interface to run code, if not you will need to use the command-line interface which is not beginner-friendly. Some IDEs can run multiple programming languages so you only have to download one IDE.

Personally, I do not like to mix my IDE with multiple programming languages. This is my setup,

  • Python: PyCharm , Sublime Text
  • Java: IntelliJ IDEA
  • Go: Visual Studio Code, Terminal

To run code, codes can be run on the IDE or through a command-line interface.

To run Python codes, you can hit the Ctrl-Enter or Ctrl-B button, or copy and paste it to Python Console depending on your IDE.

To run Java codes, you need to build the codes first to compile .java files into .class files before running them. This extra step is due to Java being both compiled and interpreted language as explained in earlier section.

To run Go codes, you can use the command-line interface and run go run file-name.go to compile and execute the code.

Alternatively, if you just want to play around without any installation, you can use an online IDE.

To master a programming language, it is best to practice it daily by doing a simple task or a project.

Learn To Ask For Help

Knowing when to ask for help is a skill youll need throughout the course of your life, not just in your coding career. The fact of the matter is, you arent going to know everything, especially when youre just starting out. The fastest and easiest way to gain the skills you need to have for a successful coding career is to ask those who have the answers. After you try to figure out the answer to your question on your own, be sure to ask someone else. Whether you do it in person or online, speaking to your mentor or teacher and listening to what they have to say is critical when you are learning to become a computer programmer.

Variables And Assignment In Java

Programming Languages, Part A

One major difference between Java and the languages we have seen so far is that Java is a statically typed language.

This means that the data types of our variables must be known and established at the time the program is compiled.

Each time we create a variable in Java code, we need to explicitly specify the data type of that variable, such as an integer, string, and so on. This is called variable .

Once we declare a variables data type, it can only hold that type of data throughout the execution of the program.

This is very different from JavaScript and Python, where variable data types are established during program execution, also known as run time. Languages like JavaScript and Python are therefore referred to as dynamically typed languages we dont explicitly state variable data types in our source code and can easily reassign a variable to any type on the fly.

In Java, we create variables using this syntax:

Datatype name = value 

Here the Datatype is the type of data that the variable will store, such as Integer, String, and so on. Next, the name represents the name of the variable we are defining so we can use it in our code. The value is the actual value we are assigning to the variable. Note that like JavaScript, all Java statements end in a semicolon.

Store Data Using Databases And Sql

A database is a program specifically designed to efficiently store, update, retrieve, and delete large amounts of data. In a nutshell, we can think of a database as a container for a set of tables.

You have probably worked with tables in Microsoft Excel. A table is just a set of columns and rows containing data. We can set up tables in a database to store the information that our programs need to work properly.

Whether we are writing programs in JavaScript, Python, Java, or some other language, we can tell our programs to interact with databases as needed.

We can retrieve data from the database to display to our users on a web page. We can accept a web sign-up form from a user and store that users information in a database for later use.

Our programs can interact with databases in real-time as events transpire in our application. To do this, most databases speak a language called SQL, short for Structured Query Language.

SQL is a programming language specifically created for databases. It allows us to tell databases what to do.

A chunk of SQL code is called a query. We can write SQL queries to fetch the data we need at a particular time or to insert new data into a specific table. Roughly speaking there are two main types of SQL queries: read-SQL and write-SQL.

A read-SQL query is one that simply fetches data from the database for us to see or use. It doesnt change the data in the database at all.
