我的最后两个elif/else语句无法执行，我不知道为什么？

我在下面的代码中的最后一个 elif 和 else 语句有一个相当简单的问题......它们根本不会执行。我是 python 的大菜鸟，所以很可能是一个简单的错误：/控制台不显示任何语法错误或任何东西......它执行代码，但结果错误

            starthandvalue = 0

            if splitfirstcard[0] == splitsecondcard[0]:
                ispar = True
                
                if (splitfirstcard[0] and splitsecondcard[0] == 'A') or (splitfirstcard[0] and splitsecondcard[0]== 'K') or (splitfirstcard[0] and splitsecondcard[0] == 'Q'):
                    starthandvalue =+83
                    
                elif (splitfirstcard[0] and splitsecondcard[0] == 'J') or (splitfirstcard[0] and splitsecondcard[0] == '10') or (splitfirstcard[0] and splitsecondcard[0] == '9'):
                    starthandvalue =+75

                elif (splitfirstcard[0] and splitsecondcard[0] == '8') or (splitfirstcard[0] and splitsecondcard[0] == '7') or (splitfirstcard[0] and splitsecondcard[0] == '6') or (splitfirstcard[0] and splitsecondcard[0] == '5'):
                    starthandvalue ==+62

                else:
                    starthandvalue ==+55

输出

['Q', 's'] ['Q', 'h']
 Hand value: about 83%
['9', 's'] ['9', 'h']
 Hand value: about 75%
['6', 's'] ['6', 'h']
 Hand value: about 0%  <--- this should be 62
['2', 's'] ['2', 'h']
 Hand value: about 0%  <--- this should be 55
['3', 's'] ['3', 'd']
 Hand value: about 0%  <--- this should be 55
['K', 's'] ['K', 'd']
 Hand value: about 83%
