Python is a very simple language, and has a very straightforward syntax.
It encourages programmers to program without boilerplate (prepared) code.
The simplest directive in Python is the “print” directive -
it simply prints out a line (and also includes a newline, unlike in C).

There are two major Python versions, Python 2 and Python 3. Python 2 and 3 are quite different.
This tutorial uses Python 3, because it more semantically correct and supports newer features.

For example, one difference between Python 2 and 3 is the `print` statement.
In Python 2, the “print” statement is not a function, and therefore it is
invoked without parentheses. However, in Python 3, it is a function, and must be invoked
with parentheses.

To print a string in Python 3, just write:

```python
print("This line will be printed.")
```

### Indentation

Python uses indentation for blocks, instead of curly braces. Both tabs and spaces are supported, but the standard
indentation requires standard Python code to use four spaces. For example:

```python
x = 1
if x == 1:
    # indented four spaces
    print("x is 1.")
```
