SumbyaggregatingcomplexpairednamesinR在R中,我尝试根据唯一ID聚合数据帧,但我需要为ID使用某种通配符值。这意味着我有这样的配对名称:123lion_tigerelephant_liontiger_lion我需要将lion_tiger和tiger_lionID相加,因为这对中的顺序无关紧要。以这个数据框为例:12df value=c("12","10","19","2","34","29","13","3","14"))因此,对ID、"1_2"和"2_1"的值需要在一个新表中求和。然后该新行将显示为:11_236有什么建议吗?虽然我的示例将数字

总结:内部函数,不修改全局变量可以访问全局变量内部函数,修改同名全局变量,则python会认为它是一个局部变量在内部函数修改同名全局变量之前调用变量名称(如printsum),则引发Unbound-LocalError在程序中设置的sum属于全局变量,而在函数中没有sum的定义,根据python访问局部变量和全局变量的规则:当搜索一个变量的时候,python先从局部作用域开始搜索,如果在局部作用域没有找到那个变量,那样python就在全局变量中找这个变量,如果找不到抛出异常(NAMEERROR或者Unbound-LocalError,这取决于python版本。)如果内部函数有引用外部函数的同名
