python2 使用s=raw_input(('do you want to know the exam period for the particular semester?') python3 使用s=input(('do you want to know the exam period for the particular semester?')

用什么?tkinter、pyQt、GTK、wxPython都可以写

printf("%d %d",++i,i++); 这个应该先算i++ 后算++i 先算的内个先提取i为0 再自加1 后面那个再自加1后提取i为2

啊哈,这个问题我尝试着解答哈.python是个非常舒服的语言,比如你这句start,stop=0,start其实已经完成了两个赋值操作1.start=02.stop=startpsp.s.这种方法有什么用处呢?在交换数字的时候特别有用比如你a=3,b=4你写成a,b=b,a 执行完后a=4,
