Pandas_对某列的内容分列

Pandas_对某列的内容分列创建数据框dic {组合: [langfang_1_11,langfang_2_12,langfang_1_13,zhangjiankou_2_14,zhangjiankou_1_15,zhangjiankou_2_16,zhangjiankou_2_18,zhangjiankou_1_19,zhangjiankou_2_20]}p_city pd.DataFrame(dic)print(p_city)输出对[‘组合”]列进行切割分列df p_city[组合].str.split(_,expandTrue)# expandTrue可以把用分割的内容直接分列p_city[地市] df[0]p_city[second] df[1]p_city[third] df[2]print(p_city)输出把分隔后的FistName都变成大写p_city[地市] p_city[地市] .str.upper()print(p_city)输出Series.str.spilt
