縮排INDENTATION

Python uses whitespace indentation(使用空白鍵縮排), rather than curly brackets or keywords(而不是使用大括號或是關鍵字), to delimit blocks(來分隔區段). An increase in indentation comes after certain statements; a decrease in indentation signifies the end of the current block.[82] Thus, the program's visual structure accurately represents its semantic structure.[83] This feature is sometimes termed the off-side rule. Some other languages use indentation this way; but in most, indentation has no semantic meaning. The recommended indent size is four spaces.
