Hey, I need your help! I did write a post about Java UI where I reference some training materials here. This will teach you Java. The only mobile programming stuff I could point you to, is Android development resources. The first time I downloaded your podcast and listened to it, the first thing i did upon opening my ipod was to download all the remaining episodes and check your website as well. Keep it up Trevor!
I hope you learn tons! Can you elaborate a little about what you mean by the scope of Java? Do you mean, where is Java used?
If so, then Java is used in web applications, mobile phones android and blackberry as well as desktop applications. Hi m very hapi that u hav explain it in very easy way…n can u explain me y we use try ; Catch; and finally block in java….. I have two resources for you to check out, one is a blog post I created that explains this concept: howtoprogramwithjava. I also have a Podcast episode where I talk about exceptions, perhaps that is worth a listen as well: howtoprogramwithjava.
Trevor — I just learned about this site listening to your interview with Pat Flynn. And mostly I just wanted to tell you that you are, indeed, a natural at teaching! You are an inspiration on how to set up a website for teaching. Well done!

We need to take into account whether or not the hungry variable is set to True or False. In order to know whether our Pypet is hungry, we are going to use an if statement. Take a look at the GIF below to get an idea of what this looks like. If the Pypet is hungry the program will set his hungry variable to False and increase his weight.
If the Pypet is not hungry then it will print The Pypet is not hungry!
Only if the condition is not met will the code beneath else: execute. Add another feed cat below your function and try feeding the cat twice to see if the function worked! Add or customize the code below under your previous Pypet dictionary. Now that we have more than one Pypet we can store them in a Python list. A list is another data type; lists stores variables in order. If python isn't the first programming language you are learning, you may have heard of this same concept in other programming languages as an array.
What if we want to feed all the pets in our list? If we want to run a function on each variable in a list we can use something in Python called a loop. The for loop in Python has the ability to iterate over the items of any sequence, such as a list. Take a screenshot of your Pypets and tweet them Thinkful so we can share your creation with the world!
Once you have completed the steps above, you should feel free to add additional features that you design yourself! Here are some ideas to get you started:. Congrats for reaching the end of this guide! For your convenience we've placed a final version of our Pypet on GitHub , if you would like to take a look at the code. If you are stuck tweet Thinkful and we'd love to help.

What is Python?
Getting your Development Environment Running To get started we'll need a "development environment", aka a place to write and execute code. Click on 'Start coding now' You will see a list of options for languages you can choose to code in.
Select 'Python' from the list You will now see your development environment. The middle panel is the Code Editor. This is where you can write and edit code. The right panel where you will see the output of your code. Create a new file containing the following code in the text editor middle panel : print 'Welcome to Pypet!
Variables Variables are a way of storing information in Python. Create this simple function by writing the following below your other code. A computer machine without a program is like coffee without sugar or a morning without the sun. Computer programs can range from two to millions of lines of instructions. There are hundreds of different programming languages. If you want to speak in many tongues, the virtual world is a perfect place for you. Computer programs are being used in almost every field from movies to medicine, defense to agriculture, entertainment to communication.
Computer programs are used for everything from medical examination to voice communication. A computer programmer is one who writes computer programs or performs computer programming.
Different programmers are associated with varied expertise in many types of computer programming language. In any programming language, the most important thing to be studied is the environment setup. This serves as a base for programming.
Robert M. Scope Case He gave the first description of cryptanalysis by frequency analysis , the earliest code-breaking algorithm. Stevenson worked with early versions of C and Unix. However, readability is more than just programming style. Software engineering.
Installation on the PC will be used to write d, compile and execute programs. The setup to start with using any programming language constitutes a text editor, compiler and interpreter. A text editor is used for creating the computer program while compiler converts the program into binary format. To execute the program directly, an interpreter is required. Certain programming languages such as Python, Perl, and PHP do not require compilation into binary format and an interpreter can be used to read the program line by line and execute the program directly without further conversion.
A single line computer program can easily be written. Different languages vary in terms of their syntax.
