+ = [J + '.' + right for J in add_dots_l (left)] RET + = [left + '.' + J for J in add_dots_l (right)] Return set (RET) Because 21 lines of Python code were used to implement a spelling checker some time ago, this equivalent but harder to read version was simplified on the rise:Def add_dots (s ): R = [s [: I] + '.' + s [I:] For I in range (1, Len (s)] R + = [J + '.' + s [I:] For I in range (1, Len (s) for J in add_dots (s [: I])] R + = [s [: I] + '.'

, only 6 bytes!-[1,] the principle is IE unique features, array processing the last item of the bug. With this approach, we can also compress the code further:New (-[1,]? Xmlhttprequest:activexobject) ("Microsoft.XMLHTTP")Undoubtedly, this is the shortest XMLHTTP creation code! Exactly 60 bytes. But compared to the normative and readability, it is recommended before that.In fact, using the Self object can c
