What this snippet does
Setting delete=False keeps the temporary file after closing, useful for generating intermediate artifacts.
Expected output
File persists: /tmp/tmpXXXXXX
Why practise typing this
Typing file i/o (advanced) code builds muscle memory for the symbols and indentation Python uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
