Dennis Sweeney <[email protected]> added the comment:
You typed `int_y = int(2.8)`, so you passed the floating point number 2.8,
which the int() function rounds down to 2.
On the other hand when y had the string value '2.8'. The int(y) call tried to
parse an integer out of the string, but failed since there were numbers after
the decimal point.
Passing a float rounds down:
>>> int(2.8)
2
Passing a string with numbers after the decimal raises ValueError:
>>> int('2.8')
ValueError: invalid literal for int() with base 10: '2.8'
Passing a string of digits without a decimal correctly parses an integer:
>>> int('42')
42
Note that the input() function always returns a string, so input() can return
'2.8', but not 2.8.
