Bingo! Coming from C# and C++, I had exactly the same realization using Python (before I switched back). I always ask Python programmers "but are you just keeping track of the types in your head?" because it's impossible to keep myself from doing that. If Python (and dynamic languages in general) are just pushing the type checking into the programmer's lap, I'm not sure what the advantage is other than less verbose (looking) code.
- gozur88 11y agoThat's the problem I had with perl. Sometimes one plus one is two, sometimes it's eleven, and the interpreter doesn't always do what you expect.
- kanatohodets 11y agoPerl has distinct operators for string concatenation and numeric addition (as well as string comparison/numeric comparison): $ perl -E 'say "plus: ", 1 + "1"' plus: 2 $ perl -E 'say "concat: ", 1 . "1"' concat: 11 There is some type funkiness: a Perl variable can have both string and numeric components. However, which one is in use is only a problem in serializers (JSON, etc.) -- in normal usage you can rely on choosing the right operator for the type at hand.
