I AIN’T GOT NO TYPE

--Originally published at Coding The Future

Personally, I am not a rap fan, but again, I am making a reference to a song. This time, No Type by Rae Sremmurd came to mind when thinking about the different types of data you can work with on Python.

Even though we've already been working with them, let's discuss these data types in more detail...

Integers: They store a whole numeric value with no decimals, e.g.: 5.
Floats: They store a numeric value with decimals, e.g.: 23.43.
String: They store a string of characters of any type, e.g.: "Hello". Note that in Python there is no char (character) type. If you wanted to store only one character, use a string of length one. Also, just like it's name suggests, it is a string of characters tied together, so you can access each character using it's position. For example, in "Hello", string[1] is 'e'.
Booleans: They store a binary value of true or false. Basically, a variable of this type can only have a value of true or false. The false value can be expressed as 0, and true as any other number. E.g.: userIsMale = false.

Also, there are types in which several items can be stored within one variable. In other programming languages, they are usually called arrays, but in python they are somewhat different.

Lists: A list that stores several variables, and can be expansible. They are not limited to just storing one type of data; or in other words, you can store ints, strings, floats, in just one list. E.g.: list = [1, 2, hey, music, 12.34]
Tuples: Similar to a list, but static. Once it is declared, it remains fixed. E.g.: tuple = {1, 3, hello}

ANSWER ME! Keeping the conversation alive…

I just realized I've been assuming in my previous articles that you readers know what output is... But I can't guarantee that.

To those of you who have been wondering what this print this, print that stuff is, here's a micro post on basic output for y'all.

Anytime you want text to be displayed when you run your program, for example, printing the value of a variable, or just a simple message, you can call the print class.

All you have to do after calling this built-in class is put text in parenthesis inside of the brackets or just the name of the variable.

Here's a quick example:

print("Hello World!")
print(userAge)

If we run this program, we will get the following (assuming userAge = 23):

Hello World
23

That's all for now. Stay tuned!

SAY WHAT? Diving deeper into Input

Sometimes people say things I don't understand. However, when programming, understanding what a user is telling you is vital in order for a program to work.

In my last post, I talked briefly about the general syntax in Python 3, but this time I wanted to focus especially on user input, because I left this information incomplete last time. Let's get going!

Basic user input

Let's recall what we learned last time. When we ask a user for input, we can ask for several times of input. The most common ones are strings, which is just text; integers, which are numbers with no decimals, and floats, which are numbers with decimals.

Strings

When asking a user for input, the first thing that needs to be done is to declare a variable where the input will be stored. In the code below, a new variable called userName is declared, and then the input class is called. The text inside of the bracket is the prompt for the user to enter their name.

userName = input("What's your name? ")

Integers and Floats

Some times, input may include numbers, and even though they can be inputed as a string, they cannot be "treated" like numbers in that situation. In other words, let's say you are asking the user for their age and it will be stored in a variable called userAge, and then you want to add 10 to the value inputed. If the user input is stored in a string-type variable, you will not be able to add text to a number. For this reason, we have to specify that the input will be of type integer. To do this, you need call the int class and insert the input class within it.

userAge = int(input("How old are Continue reading "SAY WHAT? Diving deeper into Input" →

I DON’T SPEAK GERMAN (BUT I CAN IF YOU LIKE)

--Originally published at Coding The Future

If you are a Lady Gaga fan, you are probably familiar with her famous line "I don't speak German, but I can if you like" from her song SchieBe. This lyric line has always intrigued me, but it has acquired a new meaning since I started programming. Why? Because once you learn an object-oriented language, all others come naturally in a matter of days.

I started coding on Python 3 for the first time last week, and coming from C# on Visual Studio 2008 felt like a natural transition. All the syntax is pretty much the same, and some is even simpler, which is an amazing thing!

I have taken the time to compile the most basic syntax that I've learned on Python so far. Enjoy!

1. Comments

When we think about coding, commenting often goes as an underestimated feature. Consequently, I decided to start my post with comments.

#COMMENTS: To comment, use a number sign and then write your comment.

2. Declaring variables (and arrays)

Unlike other programming languages, I've realized that on Python, you don't have to declare the variable type when declaring a variable. To declare a variable, just type the name, and if you want to, give it a value. Even though you don't need to, I usually give integer-type variables a default value of zero. You can also declare strings and arrays using the appropriate brackets.

i = 5 j = 6 k = i + j y = [1,3,5,8] x = ('Emanuel')

3. Output

To output a variable or just some text, you can use the print class. Remember you can always combine several variables or variables with text by concatenating using the plus sign.

print ('Hello World!') print ('Hello, ' + x) print (k) print (y) print (y[2])
