Python
- Source code does not declare the types of variables or parameters or methods.

- When a Python file is run directly, the special variable "__name__" is set to "__main__". Therefore, it's common to have the boilerplate if __name__ ==... shown above to call a main() function when the module is run directly, but not when the module is imported by some other module.

-We also presented 2 different ways to repeat strings, using the + operator which is more user-friendly, but * also works because it's Python's "repeat" operator, meaning that '-' * 10 gives '----------', a neat way to create an onscreen "line."

- We hinted that * works faster than +, the reason being that * calculates the size of the resulting object once whereas with +, that calculation is made each time + is called. 

- One unusual Python feature is that the whitespace indentation of a piece of code affects its meaning.
- A logical block of statements such as the ones that make up a function should all have the same indentation

- The funny thing in Python ... this code compiles and runs fine so long as the name at runtime is not 'Guido'. Only when a run actually tries to execute the repeeeet() will it notice that there is no such function and raise an error. 
- In this way, various Python modules can name their functions and variables whatever they want, and the variable names won't conflict -- module1.foo is different from module2.foo.

- You can find the documentation of all the Standard Library modules and packages at http://docs.python.org/library.
