Can anyone point out how using an int as a var is possible, unless it's something I miss that changed in 3.3 from 3.2:

david at david:~\$ python3.2
Python 3.2.3 (default, Sep 25 2013, 18:25:56)
[GCC 4.6.3] on linux2
>>> 7 = float(input('First Number:'))
File "<stdin>", line 1
SyntaxError: can't assign to literal
>>>
