Important Features of Python

Built-in high level data types: strings, lists, dictionaries, etc.
The usual control structures: if, if-else, if-elif-else, while, plus a powerful collection iterator (for).
Multiple levels of organizational structure: functions, classes, modules, and packages. These assist in organizing code. An excellent and large example is the Python standard library.
Compile on the fly to byte code -- Source code is compiled to byte code without a separate compile step. Source code modules can also be "pre-compiled" to byte code files.
Extensions in C and C++ -- Extension modules and extension types can be written by hand. There are also tools that help with this, for example, SWIG, sip, Pyrex.

Some things you will need to know:

Python uses indentation to show block structure. Indent one level to show the beginning of a block. Out-dent one level to show the end of a block. As an example, the following C-style code:
```
if (x)

{

    if (y)

    {

        f1()

    }

    f2()

}
```
in Python would be:
```
if x:

    if y:

        f1()

    f2()
```
And, the convention is to use four spaces (and no tabs) for each level of indentation.
