You can do multiple lines, just not multiple statements:

    >>> f = lambda x: x * \
    ...  20
    >>>
    >>> f
    <function <lambda> at 0x7f8b69f2c6a8>
    >>> f(2)
    40

In fact, no statements at all - just a single expression.

well, you could pack a lot of other expressions into that expression, especially with 3.8/3.9, e.g.

x,y = 1,2

q = list(map(lambda t: (tx := t*x, ty := t*y, tx+ty)[-1], [1, 2, 3]))

walrus, actually, being an expression, it's a perfect fit for lambdas
