Black window should pop up on your screen. This window is waiting for a command from you. We want to open up a Python console, so type in `python` and hit Enter.

Earlier we were working in the operating system’s command line and we could give commands. The prompt was `~$`. After running the python command, prompt changed to `>>>`. For us that means that for now we may use commands only in Python language. You don't have to type in `>>>` - Python will do that for you.

Nice! See how the answer popped out? Python knows some math. You could try other commands like:

As you can see, Python is a great calculator. If you're wonder what alse you can do...

You now created your first string! It's a set of characters that can be processed by a computer. The string must always begin and end with the same character. This may be an apostrophe (`'`) or double quotes (`"`). It has no effect on the value of the string - double quotes or apostrophes are not a part of string, they only indicate that it is a string.

Wonder why sometimes you call methods by adding `.` at the end of the string (like `"Ola".upper()`) and sometimes you first call a method and add string in parentheses? Well, in some cases, methods belong to objects, like `upper` that can only be performed on Strings. But sometimes, methods don't belong to anything specific and can be used on different types of objects, just like `len`. That's why we're giving `"Ola"` as a parameter to `len` method.

Let's try something. Can we know the lenght of a number, the same way we learn the lenght of our name? Try typing `len(304023)` and hit Enter:

We got our first error! It says that objects of type "int" (integers, whole numbers) doesn't have a lenght. Well.. so what can we do know? Maybe we can write our number as string? Strings have lenght, right?

It worked! We used `str` method inside of `len` method. `str` is converting everything to Strings.

As long as we can convert numbers into text, we can't convert text into numbers.

There is a concept in programming: variable. This is nothing more than a name for something so you can use the name rather than the something as you code. Programmers use these variable names to make their code more readable and so they won't forget what something is.

As you've noticed, your program didn't return anything as it did before. How do we now that the variable actually is there? Simply enter `name` and hit Enter:

Yikes! Your first variable :) You can always change what it means:

Yes, it's empty. Not very useful, right? Let's create a list of lottery numbers. We don't want to repear ourselves all the time, so we will put it in a variable, too:

All right, we have a list! What can we do with it? Let's see how many lottery numbers there is in a list. Do you have an idea which method you should use for that? You've know this already!

Yes! `len` can give you a number of objects in a list. Handy, right? Let's sort this list now.

This doesn't return anything... because we didn't print it! Let's try this:

Exicted for the next part? :)

The big part of programming includes comparing things together. What's the easiest thing to compare? Numbers, of course. Let's see how it works:

Do you wonder why we put two `==` next to each other to compare if numbers are equal? We use single `=` for asserting value to variables, so Python would think that we're trying to do that. You always, __always__ need to put two `==` if you want to check if things are equal to each other.

Let's give Python two more tasks:

Awesome! Wanna do one more? Let's try this:

- __and__ - if you use `and` operator, both of the comparisions have to be True in order for the whole thing to be True

- __or__ - if you use `or` operator, only one of the comparisions has to be True in order for the whole thing to be True

Accidantely, you just learned about a new type of object in Python. It's __boolean__ -- probably the easiest type there is.

Lots of things in code should only be exectured when given conditions are met. That's why Python has something called __if statements__.

Awesome, right? This way you don't have to repeat yourself everytime you want to change the name. And that's exactly why we need functions - you never want to repeat your code!
