Bug report

Actual behavior:

>>> float('\n') Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: could not convert string to float: ''

Expected behavior:

>>> float('\n') Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: could not convert string to float: '\n'

As long as the string isn't completely whitespace, it does display properly. For example:

>>> float('\nn') Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: could not convert string to float: '\nn'

In addition to newlines, the same thing can be observed with tabs and carriage returns, or any combination of the three. I didn't test any additional whitespace characters, though they would likely behave the same way.
