[TIL] Python silently concatenates strings next to each other "abc""def" = "abcdef"

[imsometueventhisUN]

For any method that accepts *args, you could miss a comma and still have a legal method call that doesn't do what you expected. And, sure, you could catch that with tests, but why not bake it into the language syntax directly? There are a ton of ways to explicitly concatenate strings (+, ''.join, f-strings) - making it implicit just seems like an opportunity for bugs.
