Depends on what you type in.

raw_input() takes a line from the keyboard (handwave) and returns it
as a string.

input() in 2.X takes a line from the keyboard and evaluates it as a
Python expression.

float() takes a string, float, int, etc, and returns the
nearest-equivalent floating point value.

What's the input you're giving to it?
