This is true. I don't think Python is to blame for it, though. Any language has potential for making a mistake that's syntactically valid but doesn't have the intended meaning. It's like when a former manager of mine typed "call me at your continence" when he meant to say "call me at your convenience".
Languages can help manage change, though, providing features such that programmers working against older dialects of the language, who make mistakes, get diagnostics according to the old version, rather than accidentally stepping on new syntax.
