我擷取程式內部分語法
把格子內數字變成變數
有格子的變浮點數
程式可以成功在背景執行
也就是使用pyqt製造出的介面後
可以成功執行任務
但是程式開啟的提示字元卻一直出現__del__
"我不知道會出現多久 沒試過七個目標點都結束他還會不會出現 所以我先來問問大大 是不是我語法宣告變數之類的沒有關閉"(因為我查的結果好像是這樣)

    

        x1=self.ui.lineEdit_2.text()  #將格子的數字換成變數
        y1=self.ui.lineEdit_3.text()

大學實習中的小小工程師!!
需要各位幫忙
或是提供意見或是可能成功的方法都可以..
因為好不容易搞出成功的程式了!!
但是一直顯示這個"del"
while迴圈內我都break了 為什麼還有就搞不懂!!!
= =!!頭好痛啊!!
