3、使用explode将一行拆分成多行 语法:pandas.DataFrame.explode(column)将dataframe的一个list-like的元素按行复制,index索引随之复制 df_new = df.explode("Genre") df_new.head(10) 4、实现拆分后的题材的统计 %matplotlib inline df_new["Genre"].value_counts().plot.bar() <matplotlib.axes._subplots...
Use the explode() Function to Explode Multiple Columns in Pandas With the explode() function, Dataframe cells with list elements are transformed to rows while replicating the index values and returning a Dataframe with the exploded lists. Before we use the explode() function, let’s create a ...
Alternatively, you can useDataFrame.set_axis()method to rename columns with the list. use the inplace=True param torename columns on the existing DataFrameobject. In case you do not want to change the existing DataFrame do not use this param, where it returns a new DataFrame after rename. ...
pandas.crosstab(index, # 行索引,必须是数组结构数据,或者Series,或者是二者的列表形式 columns, # 列字段;数据要求同上 values=None, # 待透视的数据 rownames=None, # 行列名字 colnames=None, aggfunc=None, # 透视的函数 margins=False, # 汇总及名称设置 margins_name='All', dropna=True, # 舍弃缺失...

s.index[s.tolist().find(x)]#对于len(s)<1000来说更快 s.index[np.where(s.value==x)[0][0]]# 对于len(s)>1000,速度更快 pdi中有一对包装器,叫做find()和findall(),它们速度快(因为它们根据Series的大小自动选择实际的命令),而且更容易使用。
