I’ve noticed that in IPython’s interactive shell, SyntaxError: unexpected EOF while parsing shows up if the interpreter expects more input but you send an incomplete block. For for loops, this happens if you type the loop line but forget the indented code block below it. IPython requires you to finish the whole loop block before running it. To fix this, either complete the loop with indented statements or use pass as a minimal body. This behavior helps catch incomplete code snippets early.
