I agree, and it's one of the reasons that I like the explicitness of C's variable declarations. Sure, Python makes it easier to write code; but it's easier to figure out what's a global and what's not when locals are all declared. (Yes, it's not that hard for a human to recognize when a name is being rebound as opposed to merely used, but it's extra work for a lexer/syntax highlighter.)
