So, it takes more than just integers, but it won't work the way the OP expects:
  >>> print input('Type something: ')
Type something: 'spam ' * 4
spam spam spam spam
  >>> print input('Type something: ')
Type something: y
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "<string>", line 0, in ?
NameError: name 'y' is not defined
-  because eval('y') looks for a variable named y

  >>> print input('Type something: ')
Type something: 'y'
y

It works with the quotes - it is evaluating a string literal

raw_input() would work better.
