It drops columns whose index is1or2. We can also avoid using theaxisparameter by merely mentioning thecolumnsparameter in thedataframe.drop()function, which automatically indicates that columns are to be deleted. Example: importpandasaspd df=pd.DataFrame([[10,6,7,8],[1,9,12,14],[5,8,10...

Python中pandasdataframe删除⼀⾏或⼀列：drop函数详 解 ⽤法：DataFrame.drop(labels=None,axis=0, index=None, columns=None, inplace=False)在这⾥默认：axis=0，指删除index，因此删除columns时要指定axis=1；inplace=False，默认该删除操作不改变原数据，⽽是返回⼀个执⾏删除操作后的新dataframe...
index 直接指定要删除的行 columns 直接指定要删除的列 inplace=False,默认该删除操作不改变原数据,而是返回一个执行删除操作后的新dataframe; inplace=True,则会直接在原数据上进行删除操作,删除后无法返回。 因此,删除行列有两种方式: 1)labels=None,axis=0 的组合 ...
