Its the case in nearly every language I've come across. 
And certainly in interpreted code - The interpreter has 
to know what a name is before it can use it!

Of compiled languages Pascal, C++(*) and COBOL all 
require this...

(*)C++ actually only needs a function declaration to 
precede main not the definition, but since declaration 
and definition occur at the same place in Python the 
effect is the same...
