And if you use IPython, you can use the ? shorthand, too:

    In [1]: int?
    Init signature: int(self, /, *args, **kwargs)
    Docstring:
    int([x]) -> integer
    int(x, base=10) -> integer

    Convert a number or string to an integer, or return 0 if no arguments
    are given.  If x is a number, return x.__int__().  For floating point
    numbers, this truncates towards zero.
