Summary: A lot of tests do this trick but the vast majority of them don't even call `print()`. Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file. I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives). I also corrected the additional empty lines after the import in the files that I manually edited.
