Consider using the struct module from the standard library, with format 
"f". It also allows you to specify endianness in a platform-independent 
manner, and for mixed formats, supports standard and native alignment.

http://docs.python.org/lib/module-struct.html

You have a string of length 4*n, so make a format with (for example) 
">"+"f"*n, and struct.unpack will return a tuple of length n.

For large volumes of data, the array module may be more useful (as 
someone else has already noted).
