$a = "2.3";
$b = 45;
print $a+$b;

emitting 47.3 is pretty close to what I consider "weak typing".  I
find it very hard to produce substantial, large programs using
weakly-typed languages.  Python is strongly, albeit dynamically,
typed, as you say.  Unfortunately, some seminal material of a few
decades ago confused terminology (I vaguely remember something
about it in some early article about Scheme, for example).
