Python 基于小于任何列总和百分比的行筛选数据帧

python pandas

Python 基于小于任何列总和百分比的行筛选数据帧,python,pandas,Python,Pandas,以下是我的示例数据： {'Rhesus': {('count', u'augCGP,transMap'): 6.0, ('count', u'augTM,transMap'): 11563.0, ('count', u'transMap'): 39930.0, ('count', u'augTM'): 5114.0, ('count', u'augCGP,augTM,augTMR,transMap'): 27.0, ('count', u'augCGP,augTMR'): 1.0, ('coun

正如您所看到的，其中一些类别的条目非常少。我想过滤每一行（
转录本模式
），这样，如果它们在每一列的总数中所占的比例小于1%，就会删除它们。因此，我得到的数据帧如下所示：
